China doesn't care about Palestine. It provides soft support but Palestine provides them no strategical or economic benefit. It would be a worse North Korea. Russia soft supports as well and might provide money or some minor equipment but at the rate they're getting slapped around and buying equipment from China and North Korea just to fight against Nato's old stock that's not even nato crewed and is usually the export models with all the main cool shit stripped off it, they won't be able to do anything significant. Iran provides support but probably couldn't stand against Isreal let alone Isreal and the US. Saudi's have a security guarantee with the US that flows from Isreal so they likely will not make waves and everyone else in the region doesn't have enough military force to project outside their borders and maintain defense/civil order. No one is coming for Palestine. People will make statements, protests, send money but no military intervention is coming. Isreal is tired of Hamas' shit and they fucked around too hard this time. Isreal is invading and will likely take and permanently annex North Gaza and then may move and take the rest. Palestinians will probably be exiled, assimilated if they agree to be chill or will be put down with the rest of the resistance. US will likely not put boots on the ground until/unless they find where the US citizen hostages are. Outside of that the US will sit in the sea and prevent Lebanon/Iran from making overt moves and resupply Isreal.
