I was in the west bank about a month ago. It would never work. Palestinians would riot and probably start a third intifada, or even worse. Not to mention that would start world war 3 for sure
I wouldn't imagine so, or at least it wouldn't be that bad.
It wouldn't divide up Europe, nor America or Asia.
The only ones really fighting against it would be the Palestinians and a few of the Arab nations of northern africa and the middle east.
None of them are nuclear powers, and furthermore they're currentlly riddled with their own in-fighting.
And by the quirks of the UN Security Council, Britain/USA could veto any declaration of war made by another country against us/Israel, thereby making the war illegal.
