A cycle of threat, detente and deadlock repeats itself wearisomely as the president’s war in Iran drags on

• US politics live – latest updates

As the story of the US-Iran war is written direct to social media, Donald Trump may be the genre’s premier unreliable narrator.

Since the war began, Trump has again and again threatened Iran with fearsome consequences if Tehran doesn’t come to the table and sign a peace deal that the US president said was imminent weeks ago. And he has also repeatedly claimed that an Iran deal is “close” – without any result. (A CNN tally put the number of times he’s claimed it at 38.)

The US has launched strikes against Iran after Donald Trump blamed Tehran for downing a US army helicopter near the strait of Hormuz, imperilling a shaky ceasefire that was announced by the two countries in April.

The attacks triggered a wave of retaliatory strikes from Iran on Wednesday morning, with Tehran saying it had targeted Kuwait, Bahrain and Jordan.

Donald Trump has signed a 14-point agreement with Iran, claiming it delivered a “major win” for the United States – even as it made significant political and financial concessions to Iran to reopen the strait of Hormuz and prevent a “worldwide depression”.

In extraordinary remarks on Wednesday, Donald Trump went from threatening Iran with a new wave of attacks to suggesting the country had basic rights to enrich uranium for civilian use, that he would not pressure Tehran to abandon its ballistic missiles programme and the US was “going to have to give back” billions of dollars in frozen Iranian assets.

As the adage goes: no plan of battle survives first contact with the enemy.

Donald Trump entered the war with Iran with maximalist goals: eliminating the country’s nuclear programme, destroying its ballistic missile programme and ending its support for regional military groups including Hezbollah and Hamas.

The US launched a new round of airstrikes on Iran into Thursday morning after Donald Trump warned Tehran would “pay the price” for stalled negotiations, prompting Iran to respond with strikes targeting Bahrain, Kuwait and Jordan.

The new US assault across a range of Iranian cities came as efforts to negotiate an end to the war again appeared stuck, with Iran insisting it would maintain its chokehold on the strait of Hormuz. The American attack appeared more intense and wider than the day before, but Iran released no information about what was hit.

US president says strait of Hormuz will be open from Friday but questions remain over waterway fees and Israeli breaches of ceasefire in Lebanon

Donald Trump has declared that the strait of Hormuz will be “completely open” from Friday, as western leaders gathering at the G7 summit in Évian-les-Bains battled to prevent the fragile US deal with Iran from almost immediately unravelling.

“The deal’s all signed. And the strait ⁠is already partially opened,” Trump said as he arrived at the summit in France, but Israeli breaches of the ceasefire in Lebanon and Iran’s claims about its right to charge fees in the crucial waterway revealed the agreement’s many loose ends.
