I wouldn't go nearly as far as saying that the U.S., or its government, is anywhere near xenophobic. The government isn't trying to keep us in fear, they're not even being realistic with their protection. But I do agree, fearmongering is a common tactic of politics--in this last election, the two most common arguments were that Kerry wasn't fit to handle the war (which by any and all means was true), and that Bush would rob old people of their Social Security and poor people of all their money and give it to his rich buddies.
