Level 1 - Absolute Beginner
Iran and the United States have been at war. A few weeks ago, they were trying to make a peace deal. But on June 1, 2026, Iran stopped all peace talks.
Iran said it would not talk to the US anymore. The reason is that Israel is still fighting in Lebanon and Gaza. Iran says this breaks the ceasefire agreement.
Iran also said it would close a very important waterway called the Strait of Hormuz. Many oil ships travel through it every day. When it closes, the price of oil goes up all over the world.
- ceasefire
- an agreement to stop fighting for a period of time
- peace deal
- an agreement between two sides to stop fighting and live peacefully
- strait
- a narrow body of water connecting two larger bodies of water
- oil
- a thick liquid found underground, used to make fuel and many products
- waterway
- a body of water such as a canal or strait that ships can travel through
- agreement
- a decision or plan that two or more sides accept together

Level 2 - Elementary
On June 1, 2026, Iran officially suspended all diplomatic talks with the United States through third-party intermediaries. Iranian officials said the ceasefire agreement was being violated because Israel continued military operations in Lebanon and Gaza.
Iran's Foreign Minister Abbas Araghchi said that 'no dialogue will take place' until Israel completely withdraws from Lebanese territory and stops all its attacks. Iranian state media also announced that Iran and its allies would block all shipping through the Strait of Hormuz.
The Strait of Hormuz is a critical waterway through which about 20 percent of the world's daily oil supply passes. Following the announcement, global oil prices jumped above $108 per barrel. President Trump said he believed a deal was still reachable within the next week.

Level 3 - Intermediate
Iran announced on June 1, 2026, that it was suspending all negotiations with the United States through third-party mediators, marking the most serious breakdown in diplomatic efforts since the war began. Iran's foreign minister told state broadcaster IRIB that a ceasefire 'on all fronts' was the baseline requirement, and that Israeli operations in southern Lebanon and northern Gaza constituted a direct breach of that understanding.
The statement from Iranian state media warned that 'the resistance front and Iran have resolved to completely block the Strait of Hormuz and activate other fronts including the Bab al-Mandeb Strait.' Such a closure would affect roughly one-fifth of global oil supply and could disrupt energy markets far beyond the Persian Gulf region.
Brent crude oil surged above $108 per barrel within an hour of the announcement before retreating slightly to near $106 by the London session close. President Trump told reporters he remained confident that a deal was reachable 'over the next week,' and regional sources told CNN that some diplomatic channels remained open despite the public freeze.

Level 4 - Advanced
Iran's suspension of indirect negotiations with the United States through Qatari and Pakistani intermediaries on June 1, 2026, constituted the most consequential diplomatic rupture since the Hormuz conflict began in March. Foreign Minister Abbas Araghchi, speaking on state broadcaster IRIB, declared the ceasefire 'unequivocally' violated by Israeli operations in Lebanon and Gaza, and stipulated that no further dialogue would occur until Israel completed a full withdrawal from occupied Lebanese positions and ceased all strikes in both theatres.
The accompanying threat by Iranian state media, attributed to the Islamic Revolutionary Guard Corps and affiliated resistance factions, to 'completely block the Strait of Hormuz and activate other fronts, including the Bab al-Mandeb Strait,' raised the prospect of a dual-chokepoint closure that could simultaneously restrict roughly 20 percent of global oil supply and 10 percent of global trade volume. Brent crude spiked above $108 per barrel on the news before retracing to $106 as Lloyd's war-risk premiums for VLCC transits rose to 0.57 percent of hull value.
The fragility of the diplomatic architecture was underscored by Trump's attempts to separate the US-Iran track from the Gaza and Lebanon files, an argument Tehran has consistently rejected. A senior regional source quoted by CNN suggested that Qatari channels had not closed entirely and that the announcement was partly tactical, designed to pressure Washington into restraining Israeli operations as a condition for resuming substantive talks on the Hormuz reopening framework and the nuclear dossier.
