Anyone who thinks Iran was not a threat to the US/world is beyond naive. N. Korea played the W. Bush administration and now that they possess nuclear weapons, are untouchable. Can you imagine Iran in that position? Even if the insane, apocalyptic mullahs didn’t make good on their threats to annihilate “the Great Satan” (us), once atomically armed, even with dirty bombs, they could hold the Persian Gulf hostage at will. Before your TDS kicks in, I didn’t even vote for Trump. PS- the JCPOA was ineffective as the Iranians didn't abide by it and enriched uranium anyway. Source: IAEA.
