Doubt it will get that ugly and if it comes down to nuclear weapons being used mark my words: NO ONE WINS. Oligarchs will lose their wealth and power overnight, governments will have to deal with deadly chaos that would overload their resources and strain their labor force (which would be working without pay), armed local tribal communities would form all across America in the aftermath including ex-military ex-police etc. Actually enforcing camps!? Civil war and bloodshed for all. A huge drain on the government which would collapse within a year or two.
The more likely scenario is Trump cops out due to stress and fear of the mid-term results. He'll lie and claim victory and high-tail the fuck out of the middle east and ignore it ever happened. Israel and the US will point fingers at one another. Europe's lack of participation the PERFECT mutual scapegoat lol. Europe will be blamed for not helping the US & Israel out. Political revolution will hit Europe due to their economic pain from all of this, and it will all be swept under the rug. Israel will probably see a change in government leadership too after all is said and done.
This is my prediction, let me know if anyone else has their own.
