"War"?
This isn't a war. Israel will roll up in there with heavy hardware and kill every teenager and adult on sight.
There won't be a Palestine anymore. It will all just be Israel and they'll execute or jail what little independent government was left. At best this will be another pump fake, at worst it's the end of any Islamic presence in that region. Palestine will join Kurdistan, the indigenous tribes in America and Barcelona as non existent 'nations'. That's assuming Israel doesn't go full nazi and kill every non Hebrew speaker and non light skinned Jew.
If the Muslim world genuinely cared, things wouldn't have gotten to this point. They'll leave the Palestinians to die. The only way this has a chance of ending in a two state solution or with a W for Palestine is if America is so weakened internally that there's no agreement on how to support Israel, and if the likes of China and India get involved to back up Palestinians resisting.
American politicians are on code when it comes to Israel whether democratic or republican. They always bend the knee to whomever pays them. American politicians are mercenaries that don't actually have strong ideological convictions besides "meritocracy is real and the capitalist economic model is the only way of organizing society"
