I'm sure there's good and bad folks on both sides; there always is. But, Israel can pretty much afford this bullshit pretty easily, because the know that, if attacked, big bro America will come down and bomb the other guys back into the stone age. Even if the leader of Israel were to go up, on television, put a gun to a foreign leader's head, and blow his brains out, the US would likely still come to their rescue because HOLY LAND.
In fact, let's take this "older brother" metaphor a bit further, shall we? Little brother Israel got bullied a lot when he was young, and big brother America rightly defended his little brother, and helped make the bullies stop. But, as time went on, little brother got older, and he became a bully to other people, even people who could easily wipe the floor with him, because he knew he had big brother to protect him. Big brother has a "my brother, right or wrong" mentality, and doesn't realize that his actions only serve to spoil his little brother, and encourages his bullying other people.
Big brother could do one of two things to help curb this behavior:
1) Step aside, and let little brother get that broken nose he's got coming to him; or,
2) Try and help steer his little brother away from his current ways.
I'd prefer it if we took the latter route, but, if push comes to shove, the former will serve as a good lesson to little brother Israel: Your actions have consequences, and we won't defend you if you're the one pushing the other boys into fights.
