The conflict between the United States and Iran has dramatically escalated over seven weeks, marked by a naval blockade, military strikes, and a contentious diplomatic landscape. An initial two-week bilateral ceasefire collapsed following US President Donald Trump's declaration of a "very productive Regime Change" in Iran, coupled with stringent demands for no uranium enrichment and the excavation and removal of all deeply buried nuclear material. Trump emphasized that crucial details of any agreement were being discussed "behind closed doors" and remained secret.
Prior to the ceasefire, the conflict was characterized by escalating rhetoric and military actions. In an Address to the Nation on Wednesday, April 1, Trump justified the war as "necessary for the safety of America and the security of the free world" and a response to "47 years of violence by Iran and its proxies." He claimed Iran was losing the war and begging for a deal, describing the conflict as an "investment for future generations."
Trump's Evolving Ultimatums and Threats
President Trump's threats became increasingly specific and time-bound. An initial 10-day grace period on attacks on Iranian energy plants reportedly began on March 26 (or March 27) and concluded on April 6. This was followed by a 48-hour ultimatum for Iran to either reach an agreement or open the Strait of Hormuz, warning that "all hell will reign down." On Sunday, April 5, Trump posted on Truth Social that "Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!!" He reiterated this threat on April 6, stating, "We will destroy Iran's power plants and bridges. Iran will face a destruction it has never experienced before if the Strait of Hormuz is not reopened," demanding the Strait be opened by tomorrow.
In his most significantly escalated threat on April 7, President Trump stated that the entire country of Iran could be "taken out in one night," adding that "that night might be tomorrow night." He set a specific deadline for an "acceptable" deal, including the free flow of energy through the Strait of Hormuz, for 20:00 Washington DC time on Tuesday (00:00 GMT Wednesday). He warned that if no deal was reached, Iran would face severe destructive attacks, with its power plants and bridges completely destroyed by midnight, effectively taking the country "back to the Stone Age." He emphasized no further grace period after this deadline. Trump confirmed the destruction of the B1 bridge in Karaj on April 3, stating it was "Iran's largest bridge," and claimed many short-sighted Iranian military leaders were killed in recent severe attacks on Tehran. Following the collapse of peace talks, Trump warned he could "take out Iran in one day" and later specified he could destroy the country's "entire energy system and power generation centers in an hour." Most recently, Trump issued a dire warning on Truth Social that tonight (US time) could mark the "end of an entire civilization." On April 19, Trump declared this was Iran's "last chance" to agree to a peace agreement, warning of "very severe" consequences and that the "entire country" is at risk of destruction, reiterating threats to "knock out" Iran's power plants and bridges. On April 21, Trump explicitly warned that the US would resume bombing Iran if a swift agreement was not reached by the end of the current two-week ceasefire, stating he cannot extend the ceasefire and anticipates "bomb attacks" with the American military "highly prepared and eager."
More recently, Trump warned on May 3 that the U.S. could restart airstrikes on Iran if Tehran 'misbehaves', indicating a low likelihood of accepting Iran's latest peace proposal as Iran has not yet paid 'sufficient compensation' for past actions. On May 5, he issued a severe warning that Iran would be 'blown off the face of the Earth' if it attacks American vessels in the Strait of Hormuz, as part of what he described as 'Project Freedom'. He also stated that bombing attacks on Iran would resume with "very high level and great intensity" if Tehran does not agree to the terms for reopening the Strait, linking this to the potential end of the war and restart of oil shipments.
Escalating Military Actions
US media reported the United States dropped 2,000-pound bunker-buster bombs on a large Iranian weapons depot in Isfahan, with Iran's state media confirming attacks on 'military bases.' The US military reportedly used a new, untested ballistic missile in an attack on a school and sports hall in Lamerd, Iran, on February 28, resulting in at least 21 deaths, and another missile attack targeted a girls' primary school in Minab on the same day. In a significant escalation, Iran launched its largest ballistic missile attack on Israel in weeks on Wednesday evening, April 1, just before the start of the Jewish Passover Seder night, with at least 10 ballistic missiles reportedly targeting central Israel. The US-Israel joint operation against Iran was 34 days old as of April 2. Hezbollah launched its first series of attacks on Israeli targets on April 2, specifically targeting Israeli military groups that entered Ainata city in southern Lebanon. Yemen's Ansarullah movement offered support to Iran, threatening the Bab al-Mandeb Strait, while Houthi rebels intensified attacks on southern Israel, threatening to close the crucial Bab al-Mandeb strait unless a Gaza ceasefire is agreed and the US ceases attacks on Iran. Iranian media reported an attack on a US military fuel depot on Bubiyan Island in Kuwait, which they claimed led to a US ceasefire proposal. Several large explosions were reported on Iran's Kharg Island, specifically targeting its oil export hub, hours before the US President's deadline for reopening the Strait of Hormuz. Iranian state media attributed these attacks to the 'American-Zionist enemy.' Israel's Prime Minister Benjamin Netanyahu claimed responsibility for recent military strikes in Iran, stating Israeli forces struck railways and bridges used by the Revolutionary Guards on Tuesday and destroyed transport aircraft and dozens of helicopters at an Iranian Air Force base. US Vice President J.D. Vance confirmed American attacks on military targets on Iran's Kharg Island, noting these targeted previously hit locations and do not signify a change in US strategy. On April 19, Trump confirmed that Iran had violated the ceasefire agreement by closing the Strait of Hormuz and firing shots in the Strait, specifically targeting a French ship and a UK cargo ship. On April 20, the US announced its seizure of an Iranian-flagged cargo ship near the Strait of Hormuz, which Trump stated was attacked and stopped by the US Navy in the Gulf of Oman for disregarding warnings. On April 23, President Trump issued a direct order to the US Navy to "shoot and kill any boat" found laying mines in the Strait of Hormuz, emphasizing "no hesitation" and commanding US minesweepers to triple their efforts. He also claimed that Iran possesses no warships and that 159 of its vessels have been sunk. This order was reiterated on April 28, following reports that Iran had attacked three cargo ships and seized two of them.
Recent military engagements include the US military shooting down seven Iranian boats on May 5 after reports of Tehran attacking vessels attempting to pass through the Strait of Hormuz. On May 6, Iran resumed attacks, breaking the ceasefire, including a drone attack on the main oil port of the United Arab Emirates. The US military fired on an Iranian oil tanker in the Gulf of Oman on May 7. Furthermore, the US Central Command reported that Iran attacked the USS Truxtun, USS Rafael Peralta, and USS Mason with missiles and drones, which the US described as unprovoked. In retaliation, the US launched attacks on Iranian military centers in Qeshm port, Bandar Abbas, and Bandar Korgan in "self-defense."
The Strait of Hormuz and Naval Blockade
The Strait of Hormuz has been almost completely blocked for approximately seven weeks. Iran, through General Ali Abdollahi Aliabadi, directly rejected Trump's ultimatum, calling his statement "helpless, restless, unbalanced, and foolish." Iran's Revolutionary Guard Corps (IRGC) declared that the Strait of Hormuz would "never again" be open to America and Israel. The Iranian parliament approved drafting new laws to impose transit fees for ships passing through the Strait, payable in Iranian Rial, and to restrict naval traffic from sanctioned countries and prohibit passage for America and Israel. Iran stated it would open the Strait of Hormuz if war damages are compensated. Trump initially stated that it is not America's responsibility to secure the Strait of Hormuz and that the US "will not have anything to do with" its security after the offensive, placing the burden on reliant nations. He later expressed strong opposition to reports of Iran charging fees for passage through the Strait, stating, "That is not the agreement we have!" and warning Iran to "stop now!" On April 11, President Trump announced that the Strait of Hormuz would be opened "fairly soon," with or without Iran's support, acknowledging the difficulty and mentioning other nations offering assistance. He stated that Iran had been militarily defeated and naval activities in the Persian Gulf would be restored quickly. Later that day, two US guided-missile destroyers successfully transited the Strait of Hormuz for the first time since the war began, an operation not coordinated with Tehran. The US Navy is reportedly engaged in mine-clearing activities.
Following the collapse of peace talks in Islamabad, President Trump announced on April 12 that the United States Navy would immediately begin a naval blockade of the Strait of Hormuz, targeting any ships attempting to enter or leave, particularly those that had paid tolls to Iran. Simultaneously, Iran's Deputy Speaker Haji Babai declared Iran has full control of the Strait of Hormuz, calling it a "red line" and stating that all ships transiting the waterway must pay fees in Iranian Rials. The Iranian Islamic Revolutionary Guard Corps (IRGC) issued a strong warning on April 13, stating that the approach of any military vessel to the Strait of Hormuz would be considered a ceasefire violation, and severe action would be taken, clarifying this rule applies only to warships and not to ordinary commercial ships. President Trump announced on April 13 that the United States would begin blockading ships entering or exiting Iranian ports starting at 10:00 a.m. Eastern Time. This naval blockade on Iranian ports began around 7:30 PM Sri Lanka Time on April 13, with the US Central Command stating it would be implemented impartially for ships of any country. In response, Tehran has threatened to retaliate against ports of its Gulf neighbors, and an Iranian military spokesperson condemned the US restrictions as "piracy." Trump later issued a new threat, stating the US would sink any Iranian ships that approach the US blockade in the Strait of Hormuz, warning they would be 'immediately ELIMINATED.' He also instructed the US Navy to block all ships attempting to enter or exit the Strait of Hormuz, broadening the scope of the waterway's blockade. In response, Iran reiterated it would attack any armed vessel entering the Hormuz region and warned that if the US attacks Iranian ports, no port in the Persian Gulf or Oman Sea would be safe. Iran also warned that if President Trump takes any action targeting the Strait of Hormuz, he would also lose control of the Bab al-Mandab Strait.
On April 15, Trump indicated that China is pleased with the permanent opening of the Strait of Hormuz, a move he claims was made for them and the world. On April 17, Pentagon chief Pete Hegseth stated the US maritime blockade against Iran is a "soft" policy, warning of massive attacks on Iran's power plants and energy industry systems if Iran does not agree to talks. Iran's Foreign Minister Seyed Abbas Araghchi announced that the Strait of Hormuz is "completely open" for the remaining ceasefire period, specifying that passage is on a "coordinated route" set by Tehran, which Trump confirmed and expressed gratitude for. However, on April 18, Trump warned that if a permanent agreement is not reached before the ceasefire ends next week, the US will resume bombing Iran, and expressed strong opposition to Iran's attempt to charge fees from ships passing through the Strait of Hormuz. Later that day, Trump addressed new developments, stating that Iran had reversed its decision to reopen the Strait of Hormuz today, dismissing this move as Iran "got a little cute" and cannot "blackmail" the US. He reiterated that "very good conversations" are ongoing with Iran and that such threats to close the Strait will not be tolerated. On April 20, Trump was reportedly considering removing American naval blockades around the Strait of Hormuz to facilitate peace talks, but on April 21, he contradicted these reports, stating the US will not lift its blockade on Iranian ports until a deal is reached, claiming the week-old blockade is "absolutely destroying Iran" and the US is "winning the conflict 'by a lot'." US Secretary of State Marco Rubio has accused Iran of using the Strait of Hormuz as an "economic nuclear weapon" to threaten the world, emphasizing that Washington is not prepared to reopen the waterway on Iran's terms or postpone nuclear program discussions.
On April 29, President Trump instructed aides to prepare for an extended US Naval blockade of the Strait of Hormuz, aiming to intensify economic pressure on Iran. He also engaged in discussions with U.S. oil companies to mitigate the impact of a potential months-long blockade. On May 4, Iran's military warned U.S. forces not to enter the Strait of Hormuz, following President Trump's announcement that the United States will help free ships stranded in the Gulf and guide them safely through restricted waterways. Iran stated that any military measure taken by the US would constitute a violation of the peace agreement. On May 6, Trump announced the temporary suspension of 'Project Freedom' (also referred to as 'Epic Fury'), the operation aimed at reopening the Strait of Hormuz, to allow for the finalization of an agreement with Iran. He stated that the naval blockade of the Strait of Hormuz would be lifted if an agreement is reached, but the blockade on Iranian ports would remain in force.
International Reactions and Diplomatic Efforts
Iranian President Masoud Pezeshkian stated his country was willing to cease fighting if it received guarantees against future attacks, emphasizing Iran has never sought war. He also released a letter to US citizens, urging them to look beyond "distortions and manufactured narratives." The IRGC threatened to target American tech firms, including Google, Apple, Tesla, Microsoft, Meta, IBM, HP, Intel, Boeing, and JP Morgan, citing their alleged involvement in designing and tracking assassination targets if more Iranian leaders were killed. Pope Leo made a rare direct appeal to President Trump, urging him to find an "off-ramp" to end the war. Britain deployed additional troops for defensive actions against potential Iranian attacks. However, British Prime Minister Sir Keir Starmer and French President Emmanuel Macron announced plans to form an international coalition to ensure freedom of navigation in the Strait of Hormuz, indicating a potential divergence from US policy on the blockade. Italy blocked US warplanes from using the American air base in Sigonella, Sicily, for transit to the Middle East, with Italian Defence Minister Guido Crosetto stating permission was denied due to lack of proper authorization and consultation. France, Italy, and Spain refused to provide support or airspace for United States military operations against Iran. President Trump reportedly criticized these NATO allies, calling them "cowards" and later stating that withdrawing the US from NATO was "beyond reconsideration," calling the alliance a "Paper Tiger." The US expressed concerns about China and Russia's efforts to support Iran. China's Foreign Ministry reiterated its call for an immediate halt to military operations on April 2. Widespread protests against Trump for engaging in the war occurred in major cities across several US states.
On April 1st, the US proposed a 48-hour ceasefire to Iran through another country, a proposal which Iran rejected, with Iranian media reporting the US initiated the proposal due to difficulties faced by its forces in the region. The US Embassy in Iraq issued a warning on April 2 that Iran-aligned militant groups might conduct attacks in central Baghdad within the next 24-48 hours. European Council President António Costa publicly warned that the targeting of energy facilities would be "illegal and unacceptable". The International Committee of the Red Cross (ICRC) joined international calls for de-escalation, with its president stating that "deliberate threats... against essential civilian infrastructure and nuclear facilities must not become the new norm in warfare." Iran officially rejected a ceasefire proposal, stating that a temporary agreement was insufficient and a "permanent and decisive end" to the conflicts was required. Iran reiterated its opposition to demands for the immediate reopening of the Strait of Hormuz and reportedly communicated its response to the US via Pakistan. Iran also stressed that peace talks and threats are incompatible. In response to US threats, Iran warned that if American aggressive actions expanded, the entire Middle East region could be turned into 'hell'. An Iranian official, Esmail Baghaei, clarified that if Iran's infrastructure was attacked, their armed forces would "react in kind" by targeting any similar infrastructure related to the United States. Iran's military also affirmed it would not back down from US pressure. The Israel Defense Forces (IDF) issued a warning to people in Iran, advising them to refrain from using and travelling by train throughout the country until 9 PM Iran time, citing that "presence on trains and near railway lines endangers your life." Iran's President Masoud Pezeshkian announced that 14 million Iranians, including himself, had volunteered to sacrifice their lives in the ongoing conflict. Subsequently, Iranian civilians were reportedly gathering near the country's nuclear and power plants, and bridges, to act as a human shield against potential US attacks. In response to US threats, Iran's paramilitary Revolutionary Guard warned it would 'deprive the U.S and its allies of the region’s oil and gas for years' if US President Donald Trump carried out his threat to attack Iranian power plants and bridges. The Guard also issued a new threat to Gulf Arab states, stating that previous restraints on retaliatory targets had been removed.
On April 15, President Donald Trump indicated that talks aimed at resolving the conflict in Iran could resume this week, stating the war situation is "very close to ending" and has reached its "final stage." He also stated he does not intend to extend the current two-week ceasefire and that another round of US-Iran talks could occur in Pakistan within the next two days, expecting "amazing things." Trump also announced that China has agreed not to supply weapons to Iran and that fuel and electricity prices are expected to decrease significantly once the conflict is resolved. New information revealed that the US-Iran talks that collapsed last weekend took place in Islamabad, Pakistan. Furthermore, Iran has proposed allowing ships to freely pass through the Omani side of the Strait of Hormuz, provided the United States offers certain concessions. On April 18, Iranian media, citing Tasnim News Agency, reported that Iran has not yet agreed to the next round of talks with the US, attributing this to Trump's statements regarding Iran's naval blockades and excessive demands made by the US in recent messages. On April 19, Russian President Vladimir Putin issued a strong nuclear warning, prompting Israeli Prime Minister Benjamin Netanyahu to alter some war strategies against Iran and causing Israeli forces to retreat from sensitive areas or revise operations. This followed Moscow's reported strong opposition to Israeli attacks near Iran's Bushehr nuclear power plant. Meanwhile, US President Donald Trump confirmed that US representatives will arrive in Islamabad, Pakistan on April 20 for talks with Iran.
Latest Developments
On April 20, Iranian state media, citing unnamed sources, suggested that the announced talks in Pakistan would not happen. Iran has since strongly condemned the US seizure of its cargo ship in the Strait of Hormuz, calling it "armed piracy" and vowing "appropriate retaliation." On April 21, Iran confirmed it would not participate in the second round of peace talks in Islamabad, citing the US naval blockade of the Strait of Hormuz and the seizure of its cargo ship 'Tuska'. Iranian Parliament Speaker Mohammad Baqer Ghalibaf stated that Iran will not negotiate under pressure or threats, accusing Trump of damaging diplomacy and violating the ceasefire, and warned that Iran is prepared to unveil new strategies on the battlefield. Despite this, Trump expressed optimism that negotiations "will be finalized and everybody’s going to be happy," reiterating his warning that the Strait of Hormuz will remain blocked if an agreement is not reached. Iran has declared it is not afraid of President Donald Trump's 'threats and roars' and is prepared to go to war, asserting that productive discussions could only occur if Trump ceases his policy of threats. Thousands of Iranians have taken to the streets in major cities to support their government. On April 23, Trump stated there is a high probability that the stalled peace talks with Iran will resume soon. On April 28, the White House was considering a new peace proposal from Iran aimed at ending the conflict, though President Trump was reportedly dissatisfied as it does not address Iran's nuclear program. Iran's latest proposal suggests postponing discussions on its nuclear program until after the war ends and shipping disputes are resolved, while the US insists nuclear issues must be addressed from the outset. The Iranian Foreign Minister met with Russian President Putin, with the meeting described as successful by Iran. Additionally, the UN Secretary-General has called for the reopening of the Strait of Hormuz. President Trump stated on Tuesday that Iran has communicated it is in a "State of Collapse" and wants the US to "Open the Hormuz Strait" as soon as possible while it sorts out its leadership.
On May 2, Trump warned German Chancellor Friedrich Merz not to interfere in the conflict and expressed dissatisfaction with Iran's latest peace proposal sent via Pakistan, stating he lacks confidence in Iran's ability to reach a final deal. Reports suggest the US is considering the withdrawal of thousands of American troops currently stationed in Germany. On May 4, Trump stated that talks with Iran are proceeding at a very satisfactory level, a shift from previous reports of stalled negotiations. The US is also reportedly planning to deploy troops to provide security for vessels in the Strait of Hormuz. In a related development, Israel has ordered thousands of Lebanese to leave villages in southern Lebanon, marking an escalation in the conflict between Israel and Iran's Hezbollah allies. On May 5, Trump indicated that the US military presence in the region is being strengthened and believes Iran has become 'much more malleable' in ongoing negotiations, with Israeli Defense Forces (IDF) reportedly on high alert. On May 6, Trump announced that "Project Freedom," the operation to reopen the Strait of Hormuz, would be paused for a short period to allow for the finalization and signing of an agreement with Iran, reportedly at the request of mediator Pakistan and other parties. However, he warned that bombing attacks on Iran would resume with "very high level and great intensity" if Tehran does not agree to the terms for reopening the Strait. Iranian President Masoud Pezeshkian stated that the US continues to pursue a "policy of maximum pressure" and that Iran cannot comply with unilateral US demands. Despite Trump describing talks as 'very good,' negotiations since the April 8 ceasefire have reportedly yielded no concrete results, and tensions have risen again.
Economic Impact
Global crude oil prices initially saw significant drops following Trump's remarks about de-escalation, but later rose after his speech, with Brent crude increasing by 4% to $105.38 per barrel and U.S. West Texas Intermediate (WTI) crude futures for May gaining 4.1% to $104.21 a barrel. Following Trump's statement on April 3 that the US had "only just begun" destroying what remains in Iran, Brent crude oil prices surged by approximately 8%, surpassing $109 per barrel. Overall, global crude oil prices have increased by nearly 50% since the conflict began, contributing to global inflation. The recent naval blockade has further caused oil prices to surge. Gold prices initially rose to a nearly two-week high but later reversed course, with spot gold falling 1.3% to $4,694.48 per ounce and U.S. gold futures sliding 1.9% to $4,723.70 on April 2. Asian stock prices rose following Trump's statements about a potential withdrawal from the Iran conflict, but global stock markets later saw significant drops after Trump's address, as investor confidence was shaken.
Other Developments
Trump claimed Iran had provided 10 oil tankers to the United States as a gesture of goodwill. Iran's Supreme Leader Mojtaba Khamenei called for a comprehensive national effort to restore infrastructure and address the destruction caused by "unprovoked American-Zionist aggression." Iran also declared that its nation "cannot be crippled." Legal experts have raised concerns that Trump's threat to destroy all of Iran's power generation centers could constitute a violation of international war laws. President Trump's address to the nation occurred an hour after NASA's 'Artemis 2' mission successfully launched, with Trump congratulating the astronauts before discussing the war.
