Also why do you have everyone hatin' on Israel.
Can I request you give them a chance of survival? Like maybe giving them a few more divisions?
Yeah, while I'm without internet I'm planning on letting the game run for a few months to see what happens, and if one side gets utterly hammered straight away I'll balance it somehow then reload.
Or maybe a Deus Ex Machina will pop up and the war ends
Edit: Officially in-story though, it's because they've already gobbled up Jordan, Syria and Lebanon and have the backing of the Western powers and the rest of the states that aren't allied with that powerblock are worried about having a growing power in their backyard.
