Bowen: Trump needs this war to end but Iran is not backing down

The United States and Iran have both signalled that they would prefer not to go back to the war that has been on hold since the ceasefire was announced on 8 April.

Neither side has allowed the steady drumbeat of military exchanges between them to end the talks being mediated by Pakistan, Qatar and others.

The US still has powerful naval and air forces within striking distance of Iran.

It is safe to assume that the Iranian regime will have kept its forces on high alert and will be using the ceasefire to re-organise and repair damage done by the US and Israel.

Armed tension in the area in and around the Gulf opens up a clear risk for both sides of miscalculation and misperception.

The US is trying to keep the pressure on the Tehran regime to make concessions by demonstrating that they are close by and capable of causing great damage.

The Iranians are reminding the US that their determination to resist is undiminished and, if necessary, they will attack American bases and the wider infrastructure of the Arab gulf.

The first objectives on what would be a long and perhaps unreachable road to a wider deal between the US and Iran is a continuation of the ceasefire and an agreement on a "memorandum of understanding" on the agenda of more talks between them.
