Donald Trump has boldly tied negotiations to end his war with Iran to a swathe of Arab nations formally establishing diplomatic ties with Israel.

In a 565-word post on his Truth Social platform, the US president made the demand that he was “mandatorily requesting that all Countries immediately sign the Abraham Accords”.

That is the name he gave to the policy of Arab states normalising relations with Israel during his first term in office.

Mr Trump has made no secret of wanting to see some of the region’s biggest players establish diplomatic relations with Israel, but little progress towards that has been made.

Before the war, Saudi Arabia, for example, had refused to consider it unless Israel allowed for a Palestinian state and withdrew from occupied territory.
