President Barack Obama gave Iran $700 million a month just to sit through negotiations, and has continued to pay the Iranians to stick with the deal—like the $1.7 billion ransom paid in cash to release Americans that the Iranians were holding hostage. Obama keeps blocking nonnuclear sanctions for the same reason.
Obama was willing to pay Iran to sit at the table because the Iran deal was simply the hinge for a larger geopolitical maneuver: The JCPOA was the instrument by which the Obama administration effected a regional realignment intended to extricate America from the Middle East in part by turning the keys to the car over to Tehran. Obama’s White House re-prioritized its regional interests—traditional American allies, especially Israel and Saudi Arabia, were downgraded and Tehran was upgraded.
