Why the USA is so concerned about Israel and the well being of the state of Israel?

Think of it like this:

Israel = little Tommy Britain = Mommy USA = Daddy

Now Mommy gave birth to little Tommy right after WWII. Little Tommy is precious to Mommy because little Tommy is a sign of good Mommy can be. Now unfortunately for little Tommy he sent to school with a bunch of kids that weren't too happy with his birth because one of their friends died so he could be born. Now instead of playing it cool and trying to make friends, little Tommy starts boasting about how awesome he is and how Mommy (and subsequently Daddy) are always there to protect him and how much better he is than everyone around him and honestly being kind of a giant douche. Well when the other kids start to get physical in reaction to little Tommy's verbal abuse. Little Tommy goes running home to Mommy crying about the mean bullies who want to beat him up. Well Mommy is all powerful and loving and can't let that happen, but at the same time she herself can't handle something like this; she needs someone more powerful, stronger and better equipped for bullies. So she enlists the help of Daddy. So now anytime Little Tommy starts to dick around and pisses off the other kids and they start to fight. Little Tommy runs to Daddy and Daddy pulls out his big stick (TR reference NOT a penis joke.) and starts waving it at the other kids threatening to whoop their ass even though it's his and Mommy's little shit that is starting all the problems.

There you go a simple version of relations in the middle east. While there is wrong doing on both sides of the argument it is my firm belief that Israel starts more shit than they need too and just run to the US because they can. Also something I didn't throw in their is guilt for the Holocaust. But that can be more or less debated.
