Honestly the Israel & Palestine situation is a complex version of 2 little kids not wanting to share their sandbox with each other. Each of them saying it was mine first when they could easily divide it equally. Unfortunately one of them has the sandbox bully on their side so the other boy has no chance.
Not as simple as that. The Israelis are having USA on their side, but Barack Obama is not as much pro-Israeli as his predecessors. On the other hand, emerging powers such as Saudi Arabia and Egypt are supporting the Palestinians.
Eqypt is not really pro Hamas they just had a brutal crackdown on the Muslim brotherhood (the father organisation of Hamas). Saudi I'm not sure, they do everything hidden but they are also allied with the US.
its more like a playground where all the kids are kinda friends with each other but allegiances change very easily.
to take the analogy further..
the chubby Isreali kid kicks over the Palestinian kids sand castle and then begins sitting on the skinny little Palestinian kids head and when the little Palestinian kid tries to fight back he gets punched in the face.. when the teacher comes to stop the fight, the Isreali kid says to the teacher "he started it... I was just defending myself miss..", "I have a right to defend myself because this is
my sandbox that god gave to
me.."
