The US president, Donald Trump, is weighing up whether to join Israel in attacking Iran. The fact he is even contemplating such a move is, in my opinion, a direct consequence of his 2018 decision to tear up the agreement negotiated during Barack Obama’s presidency that limited Iran’s nuclear capabilities in return for sanctions relief.
Trump not only squandered the opportunity to constrain Iran’s nuclear ambitions severely. He also shut the door on showing Iran that diplomacy and economic development could offer a more promising path than proxy warfare.
The Obama administration’s core strategic rationale behind the 2015 Iran nuclear deal, or joint comprehensive plan of action (JCPOA), was that amid several devastating regional wars and an American public weary of costly military interventions, a war with Iran would be disastrous. This was especially true given the growing US desire to pivot toward containing China.
