Trump’s Iran deal is result of unrealistic ambitions for an untenable war

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.

He exits it with Iran’s word not to build a bomb and to hold further nuclear discussions, no mention in writing of the ballistic missiles programme and with Hezbollah celebrating a “victory” as the memorandum of understanding (MOU) instituted a ceasefire in Lebanon, where Israel has seized a swath of the country as a “buffer zone”.

Iran’s key asset ended up being the strait of Hormuz, the waterway that almost every previous simulation of the war predicated would be quickly cut off by Iran. To reopen the strait, the administration was forced to fold on its broader goals or face what Trump called a “worldwide depression”.

Barbara Leaf, a distinguished diplomatic fellow at the Middle East Institute and a former US assistant secretary of state for near eastern affairs, said the US had started the war with “disastrously unrealistic assessments of the regime’s resilience”, as well as Iran’s readiness to seize the strait of Hormuz and attack US and foreign facilities in the Gulf.

“The US rapidly found that overmatching an adversary that has spent four decades honing its asymmetrical warfighting doctrine and skills would not be the war it had prepared for,” she said. “And the rapid escalation of economic pain globally that eventually came to American consumers made the war all the more untenable.”

Now, she added, Trump faced a conundrum: “He doesn’t want to go back to warfighting. But he’s tossed away so much of the leverage he might have had if the war had ended in the first or second week.”

It has been clear for days that the Trump administration was skittish about putting out the text of its memorandum of understanding (MOU). It was only finally read out by a senior administration official on a briefing call on Wednesday, and the White House still has not published a copy online.

The reasoning is clear: many in Trump’s own party will hate this deal. The outgoing US senator Bill Cassidy, of Maryland, called it the “worst foreign policy blunder in decades”.

“Reagan is rolling over in his grave,” he wrote. “Iran’s nuclear ambitions were not curbed, and they have learned that threatening the strait of Hormuz works and will undoubtedly leverage it in the future. Now, Iran gets to build brand-new infrastructure under this deal.”
