Ron-
The fact is that, despite a fallen dollar which makes visits to the US
an unprecedented bargain for visitors, tourism to the US has decreased drastically, while tourism to other places has gone up.
I've traveled abroad, and I'll flatly say that the treatment of people entering the US is markedly ruder, more officious and unfriendly than that of people going to, say, England.

Our system of "defence" against terrorists has been demonstrated to be ineffective; it's also demonstrated to be irritating and obnoxious.
