Israel was successfully defanging Iran's terror programs. That's in fact the entire reason this war exists. It was Israel's plan. This is all their retaliation for Oct 7th.

So why the hell are we there? We didn't build a coalition. We didn't really justify our involvement. Trump and Trump supporters insisted on isolationism, pulling back from being the world police, ignoring even heinous invasions like Ukraine to save a few pennies, but suddenly Iran has insulted us through its existence for far too long?

Bullshit.

Keep in mind, Iran was likely to evolve in some way in the next few decades as a result of their impending water crisis. Waiting for a better opportunity would have been the smart choice.
