Hundreds of thousands of Saudis didn't immigrate here to escape certain death.
There's also the fact that America is still a very religious country - and takes it seriously - so many people support Israel because they really do believe they're protecting God's chosen people. No one should "wish" for war, but I've often wondered what would happen if Saudi Arabia decided to wage war against Israel. I'm very curious with whom America would ultimately side.
From what I understand, there is also a surprisingly large base of devout Christians who support Israel in the hopes/belief that it will lead to a prophesied battle at Armaggedon, helping to usher the end of the world. Apparently [0] George Bush Jr. may have been a believer in this theory (though others dispute this: [1])

Some of this stuff makes the blood curdle. If it was spewed by some guy in a turban the US would probably have had him killed with robots from the sky by now...

Even that's stickier than it initially appears, in that some of the American evangelical supporters of Israel do so because they think it's necessary to start the End Times.

These prophesies don't actually end well for the Jews.
None of theses superstitions end well for humanity.
Not all apocalyptic thinkers get a reasonable shot at the nuclear codes of the world's primary superpower every few years, though.
“My father would say, were he a Jew, he would never, never entrust the security of his people to any individual nation, no matter how good and how noble it was, like the United States.”
The balfour declaration was signed well before the holocaust had ever happened; using the holocaust to justify the creation of the colony if israel is anachronistic at best.
Granted, British Israelism would morph into an even more insane (and downright misanthropic) off-shoot, but you know, humans gonna human I guess. I think these attitudes about Israel have existed for quite a long time anyway.
