What's the point?

Say the goal is to get rid of the regime by giving the protesters an opening to rebel. Then Trump blew the metaphorical load too early by encouraging the protesters on truth social. Tens of thousands of them being killed destroyed the momentum. Smarter people would have tried to arm them first, or discouraged the protests until we could hit them at the same time.

Say the goal is to "do the right thing." Then we shoudn't be tag-teaming with a country doing a genocide, clearly. We'd probably be hesitant to help them destroy their enemy or realize their interests in general. We've had endless opportunity to reign them in and done nothing about it. "Oh, but we need them to project force in the middle east for us." Well then why the fuck are we starting a war? Let's force that ally to reform before starting the war. There was no fucking rush man.

Say the goal is to prevent Iran from obtaining a nuclear weapon. Well, Iran isn't (wasn't) run by stupid people. They knew we could likely set back their nuclear program before it completed and they knew the best-case-scenario in building nukes would be to get some leverage. They therefore opted to take a deal, using the threat of becoming armed to have some leverage. For us this is a great deal because we don't need to pay the costs of fighting Iran and we don't need to give them a better deal at nuke-point, and for them it's pretty solid because it's less risky. There's no evidence the terms were violated before WE ripped up the deal.

"Well however we got into this situation, we're here now and they could have nukes within seconds, I mean minutes, I mean hours, I mean days, I mean months, I mean years..." Maybe before creating an international energy crisis, just bomb the damn nuclear program again. Worst case scenario they get a nuke and what? The whole point of a nuke is leverage, when you use it you lose the leverage. We would be forced to cut another deal with better terms for Iran. Whatever dude, maybe that's not worth fighting another middle eastern war idk maybe I'm crazy.

I'm not a big war guy who just loves killing for the fun of it or whatever but even a war of aggression can be competent. I can admit when competence is exhibited and when something I otherwise dislike at least works out well. This shit is the most monumental blunder in decades. It wasn't planned, it has no goal, it will either end in a pointless withdrawal or (most likely) a Vietnam-esque quagmire. Every single problem was foreseeable and foreseen, that's why we didn't do this before. But some fucking moron pedophile gets blackmailed hard enough by a genocidal war criminal to say "what's one more, for old times sake?" and I'm supposed to want to shout hurrah and put my goddamn body and soul on the line for absolutely literally jack shit? Utterly ridiculous.
