I find it interesting that most of the comments here are not from people from the US. Seem to be just a bunch of American-bashing.

Personally, I don't think of the US President as the "ruler" of the United States. He/she is more like the chief representative of all the states, and if you look at the very short history of the US, its amazing that 50 individual states (which each have their own governor) can have relatively peaceful presidential elections every four years, which often times results in not only a change of power but a completely different way of going about the nation's business.

I have no idea about Israel or the Jewish people in America. Then again, I am from a state that doesn't have much of a Jewish presence.

On a side note, I get rather confused when a religion is equated to a nation. I don't think of the Muslim people as one nation nor do I think of the Jewish people as one nation, but they are individual people practicing their own religions. This way of thinking (and separation of church and state) is in the US constitution, but it is something that many who have country-wide religions just don't understand.
