I hope Iran goes full 𝒹𝑜𝓃𝓀𝑒𝓎 𝓀𝑜𝓃𝑔 𝓀𝒾𝓃𝑔 𝓀𝑜𝓃𝑔 𝒸𝓇𝒶𝓏𝓎. One more front is what the war always needed to look very different. I doubt Israel could adequately take on Hezbollah, let alone Iran itself. Things escalating will break the Israeli military and economy in ways they can't get out of any more than Ukraine can.
That's exactly what I think would happen. Ukraine has eaten up the surplus of the things we'd need to fight a protracted war against Iran. The US Navy's urgent priority is East Asia and they barely have the ability to cover that in peacetime. Support for Israel is becoming increasingly unpopular with the electorate, while Zionist liberals have been so weird and disgusting that I would never consider voting for a John Fetterman or Bernie Sanders. Only the US Marines are currently reaching their recruiting goals, and the first month of that war is going to produce drone videos that immediately turn off potential volunteers.
Iran would be such a serious near-peer war at such a bad time that I don't see the US being baited into a general invasion to support Israel. Maybe they're stupid enough but that's the kind of war that would break the empire.
I always laughed at the US invading Iran. There is just no way America could actually take Iran in any way. The hills of Afghanistan turn into the mountains of Iran. Tehran is a fortress pretty much. There is no victory there, only dumbfuck Americans getting owned by a mountainside ambush.
Iran has the IRGC, an entire branch of the military dedicated to asymmetric combat. The Yankees would be getting fucked before they even landed and then every step of the way towards Tehran. If it was even possible to take Tehran the Iranians wouldn't just give up either. It would be historical farce if it wasn't for the inevitable destruction the Americans would cause.
