Middle East crisis live: Donald Trump says Iran shot down military helicopter and US ‘must’ respond

‘The United States must, of necessity, respond to this attack’, the US president said in a social media post

Donald Trump and Benjamin Netanyahu are close allies with a deeply complicated and often strained relationship that has shown signs of fracturing over recent days. The Guardian’s senior international correspondent, Julian Borger, has looked into how the two leader’s diverging political priorities are undermining ceasefire negotiations. Here is an extract from his analysis piece:

Trump and Netanyahu went to war together against Iran on 28 February but fell out of step within days, as soon as it was clear that the quick victory and regime change promised by the Israelis was unlikely to materialise. From then on, their interests have increasingly diverged.

Once Iran closed the strait of Hormuz, the spike in the oil price and the interruption in the flow of globally traded chemical products became a political threat to Trump. Despite Republican gerrymandering and voter suppression, Democrats have a plausible shot at capturing at least one chamber of Congress in November elections, undermining his authority. More immediately, the president would clearly prefer to steer clear of global distractions while he hosts football’s World Cup.
