Trump Gets His Iran War
By 
The JCPOA’s vulnerability was inherent to its nature; as an agreement designed to avoid war, it left both the United States and the Islamic Republic with some things that they wanted and others that they did not.
American critics decried the fact that Iran’s missile and militia programs remained untouched, and made a series of deeply deceptive claims regarding the agreement’s “sunset” clauses.
President Trump’s decision to unilaterally abrogate the agreement left nothing in place but an abiding sense of distrust among the Iranians.
Had Trump remained in office after January 2021, war might have come earlier, but in any case, the powder keg had been positioned, and the fuse was ready to be lit.
Efforts to re-establish the agreement during the Biden administration failed because of Iranian distrust and a sense that strenuous diplomatic efforts would not pay off at home.
Most things in international relations are complicated. This one is not; the war was fully avoidable and President Trump is wholly responsible for failing to avoid it.
