Israel helped us when we were hit in NYC a few years back with American Air planes that were packed with Americans with re to who, what, when, where, and why those planes hit the WTC. That helped us immensely in preventing another 9/11. Had they said "Why can't America take care of itself," we'd have strike after strike until our investigators found out who what when where and why.
They are one of our strongest allies, and were we shocked when we found out they lost 6 million people in WWII, so we went to bat for them at that time. The same people who killed the 6 million Hebrews went on to the next generation of beating up on America on 9/11. It wasn't clear to us who did it at first. Our allies in Israel made sure we were totally informed at an expense of time and life to them. Now the Hitlerian participants in WWII from the Middle East have bombed out Israel, and we're simply returning the favor.
We could be next, unless they obliterate Israel entirely. We'd be stoopid not to help Israel, and you can't fix stupid once it convinces you doing nothing is the thing to do. The Nazis alligned themselves and used Arab countries in WWII with the promise that after the Nazis were in control of Europe, Hitler told them he'd "clean up" the Arab lands, too. It was the bargain made in hell, and if we don't help Israel, they won't be around because genocide is the Nazi way, and the Arabs got infected since they weren't too keen on Israel ever for thousands of years.
