Did you happen to notice that while Iran's cash flow is on, Hamas attacks Israel, and then when it's off, they mostly don't?Iran nuclear deal.
Trump was working on (really, continuing the work of his predecessor) withdrawing from Afghanistan without major incident. It was the Biden administration that bungled that.The withdrawal from Afghanistan. The betrayal of the Kurds. The withdrawal from the nuclear treaty. And the assassination of Soleimani, while not bungled, was a strategic misstep that escalated the risk of regional war.
Did Assad genocide the Kurds? Wasn't that supposed to happen? Trump pulls US forces out of Syria, leaving the Kurds behind, and then they get murdered by Assad? Oh, that was imaginary. Looking at current headlines, Assad's current big thing is not supporting Israel in a war people here consider genocide. Do you ever look back on things and think "well, I was wrong about that", or do you really just assume that the things you predicted came true?
The nuclear treaty was stupid. It was "in exchange for not developing nuclear weapons, we will give you all the power and ability to sow chaos around the world that nukes might hypothetically have given you."
And "escalated the risk of regional war" is such a dumb thing to say looking back. Your ideas about what is probable are purely made up, and we have hindsight. A new administration came in and changed to less aggressive policies, and major wars broke out in multiple places. Trump assassinated a guy, and the rest of the region was signing peace treaties.
