I never said the US created the tension, I'm just saying their involvement in the whole affairs worsens it. Besides, the US never promised their homeland - the UK did that. The holy war over Jeruzalem has been thought between Muslims and Christians - not Jews; that's something of recent times.
The American - financial - backing for Israel comes mostly from private Jewish-American people. The Jewish community in America is relatively VERY powerful and VERY rich. They have a lot of influence and surely they want to back their kind in the Middle-East. That's the reason Israel is so rich (compared to the countries surrounding it).
American involvement in the Middle-East has a twofold affect on the whole situation there. Firstly, because America made Israel rich (I know this is a very bland thing to say), Israel can act the way it does now: very cocky (also because they know they got America on their hand of course). Secondly, because America is involved other Middle-Eastern countries, especially Iran of course, have a very different approach to the whole matter. Like most of you will know, most of the Muslim world, especially the Shia, aren't very fond of the US. The result is that they want to destroy their (the US') ally in the Middle-East. Now that Egypt isn't an American ally anymore, nor is Turkey as much as it used be, the Muslims have a pretty big geopolitical advantage. Especially Iran is scary and I wouldn't be surprised if the conflict will get out of hand soon.
Honestly, I don't believe there would be a Jewish land in the Middle-East still if it wasn't for Western-European and American help: the Zionists would have been expelled a long, long time ago.
And to Ryan I can just say:
