Just so you know, Obama gave them pallets of cash (1.7 billion dollars) Trump pulled out of the Iran nuclear deal saying it wouldn’t stop them from making nuclear weapons (it wouldn’t have) put sanctions on them and no one did business with iran except North Korea illegally, then Biden gave the 6 billion dollars in frozen assets and lifted sanctions sanctions on two Iranian entities involved in military missile programs in 2021 for example. Keep blaming Trump though.
Obama did not “give” them cash, that was their own money, that we froze with the Office of Foreign Assets Control, and we then unfroze after they agreed to stop enriching uranium. The plan was perfectly verifiable, Trump revoked it not bc it wasn’t, but bc he wanted to undo Obama’s foreign policy. And also bc the Israelis told him to.
