For five days in a row as of July 16, 2026, the United States and Iran attacked each other across the Persian Gulf, a major body of water between Iran and the Arabian Peninsula. The strikes also affected nearby Gulf nations and Jordan. Both countries said the ceasefire they had agreed to in June 2026 was no longer in effect (Al Jazeera).

A ceasefire is an agreement to stop fighting, usually to give diplomacy a chance. The June agreement, called the Islamabad Memorandum, was signed on June 17, 2026. It extended an earlier ceasefire and committed both sides to peace talks with Pakistan acting as mediator, a go-between who helps two sides negotiate.

That June deal followed an earlier ceasefire agreed on April 8, 2026, which was initially meant to last two weeks. It was extended and held until July 8, when fighting resumed. The June agreement came with real concessions from both sides. Washington called off its naval blockade (when warships prevent ships from entering or leaving a country's ports), issued a 60-day waiver on sanctions (economic penalties meant to pressure a government), and promised to unfreeze Iranian assets. The Iranian currency, the rial, rose 15 percent the day the agreement was signed. Iranian Foreign Minister Abbas Araghchi signed the deal aimed at turning the ceasefire into lasting peace (Le Monde). Oman's Foreign Ministry welcomed the announcement.

The agreement fell apart in stages. By July 9, AP News reported that exchanges of fire across the Persian Gulf were intensifying and threatening the deal. On July 13, CBS News reported US strikes on Iran in retaliation for an attack on a commercial ship. In the week of July 13, Washington re-imposed sanctions after the 60-day waiver expired or was revoked. On July 14, the State Department published an action described as "Dismantling Shamkhani's Illicit Shipping Empire," followed on July 15 by an action targeting people who help the IRGC (Iran's Islamic Revolutionary Guard Corps, a powerful military force) obtain weapons (US State Department). Iran's foreign minister said the United States had violated the agreement (Iran International). Renewed US strikes targeted Iranian military sites including the strategic island of Greater Tunb.

The language from both sides got sharper as the fighting escalated. President Trump said in the days before July 16 that Iran was "desperate" to make a peace deal but that he did not trust Tehran to keep an agreement. On July 15, Iranian lead negotiator Mohammed Bagher Ghalibaf said Iran was "in an existential war with America" and had no reason to keep following the peace agreement. On July 16, Pakistan's Foreign Ministry spokesman Tahir Andrabi urged both parties to end attacks and pursue dialogue.

The June 2026 agreement did not come out of nowhere. In June 2025, a joint US-Israeli military operation largely destroyed Iran's nuclear infrastructure, according to the Council on Foreign Relations (CFR). The US said it significantly damaged Iran's nuclear sites during a 12-day war in 2025, an operation the State Department's legal adviser later documented as "Operation Epic Fury" (US State Department). A ceasefire followed to allow diplomatic negotiations. The White House in August and October 2025 published releases celebrating Trump's diplomatic achievements, referencing "Peace Through Strength in Iran" and "The Trump Declaration for Enduring Peace and Prosperity," dated June 19, 2026 (White House.

The region is crowded with overlapping conflicts and agreements. In June 2026, the US, Lebanon, and Israel issued a joint statement in which Israel and Lebanon agreed to implement a ceasefire through US-led negotiations (US State Department). After the US announced its ceasefire with Iran, Israel conducted bombardment of Lebanon (Britannica), showing how fragile and connected these arrangements are.

The economic and military numbers show how uneven the matchup is. Iran's GDP per capita (the average economic output per person) fell from $8,000 in 2012 to $5,000 in 2024. Oil exports dropped from 2.2 million barrels per day in 2012 to 1.5 million in 2025. By April 1, 2026, Iran had used up 30 percent of its pre-war missile stockpile and 60 percent of its drone arsenal, according to CSIS analysis cited by Al Jazeera. The 15 percent surge in the rial when the June agreement was signed, followed by sanctions being re-imposed, captures the whiplash Iran's economy has absorbed.

The broader question Al Jazeera's July 16 analysis poses — who needs a new truce more — depends on what each side can keep up. Iran's shrinking weapons supply, contracting economy, and destroyed nuclear facilities make continued fighting very costly. But Ghalibaf's description of an "existential war" suggests a regime that may believe surrendering would cost more than grinding on. On the US side, Trump's public distrust of Tehran limits his room to negotiate. Calling the adversary "desperate" while re-imposing sanctions and striking Greater Tunb is a posture aimed at domestic audiences as much as at Tehran.

Pakistan's role as the main mediator stands out. Islamabad has placed itself between two parties whose trust in each other is effectively zero, and Andrabi's July 16 appeal suggests the communication channel remains open even as both sides reject the agreement. Whether that channel can produce a second deal when the first collapsed in under a month is the key question, and neither side's current language offers much reason for optimism.
