This could go down as Trump's biggest f-up. For the sake of our Israeli allies, hopefully it won't.
Why would Iran bother staying in? They're getting none of the benefits and still playing by the rules... Trump is playing a short term game to punish Iran (God knows why). His Iran foreign policy is easily the biggest blunder of this administration, and that is saying a lot.
You both seem to be missing something here. You're writing as though you think Trump is attempting to act with some long term strategic goal in mind (even if it may be one you don't agree with). That is not how Trump operates.
Trump does the Saudi's (
who can pay him and his family) a favor by re-imposing sanctions on Iran. And he gets some PR capital here in the US at the same time . And he gets to wreck something Obama did. Win, win, win for Trump.
Sure, wrecking the Iran deal has a cost. He's spending US credibility and goodwill, and maybe peace and lives too. But Trump won't be paying those costs. Others will. Spending others capital for his own gratification while escaping personal consequences is what Trump
does.
