Personally, I don't think Gaza will exist after this. Iraq and Iran could possibly merge. Not sure what to make of China. They'll definitely see an increased level of internal conflict in the short term. Not sure if we'll see a civil war of sorts. But, we'll see. The Saudis might force a merge with Kuwait. Not sure about Argentina. Brazil will see a secession of multiple states. Texas might secede from the U.S.
