And let's say this cosmic eldritch force will pretty much do the same to any further attempts to create an "Israel". So they pretty much rip Israel out of existence, with the "International community" being unable to do anything to preserve or support Israel.
Do you think the "international community" will just shrug their shoulders and move on, because let's be honest there's nothing they can actually do against some cosmic metaphysical eldritch force beyond their realm of comprehension...
or... do you think they'll band together and do whatever they can to create another "Israel" despite what I said above? And attempting to do so will pretty much destroy them, but for them it'll be worth it because the very existence of an "Israel" is more important than their self-preservation; they straight up can not live in a world without "Israel"'s existence.
In addition, what do you think the U.S. will do? Do you think they're going to try fucking airstriking Cthulhu or something? Or let's say, they snap their fingers and proxies appear out of nowhere, they spawn in pre-armed and pre-trained, and they immediately do a regime change on Cthulhu or something. Or Idk something something dollar hegemony.
OK. Let's just say Israel just collapsed and handwave away whatever specific means that the eldritch horror used to instigate it. My prediction is the Samson Option is used, the whole region gets nuked.
If Israel's nuclear weapons were removed as part of the collapse process, then I think that the whole region would be a repeat of the partition of India and Pakistan, since you could squint really hard and say that the UK was an eldritch horror and they did this exact thing when they left the region. An incredible ethnic cleansing on both sides, but I think that the United States would absolutely fall all over itself to step in and try and occupy that vacuum. Even though the US is there already and can move quickly, I think it would be an absolute bloodbath. I think the US and the remnants of Israel would prevail, but it could easily spiral out of control and trigger nuclear conflict across the world.
