The most striking aspect of the US campaign for regime change in Iran is the repeated US insistence that Iran must negotiate. Iran has negotiated, repeatedly. The JCPOA was negotiated and ratified by the UN Security Council. Even after Iran engaged in renewed negotiations last summer, it faced large scale air strikes on its territory. Now, the US openly avows the policy of economic collapse and regime change.
There is no way the US gets anything done in Iran. Its not an easy place to attack geographically. Sure they can drop some bombs and guns and cause chaos. But there doesnt seen to be the support for American regime change and America cannot put boots on the ground.
Trump has a magical talent to always pick the worst possible choice. Its like hes sabotaging.
