I was yesterday night discussing with an american friend living in Paris. By the way, he really enjoys it and never perceived any kind of bitterness or even threat because of the US politics; when some media or people on the other side of the Atlantic say it's dangerous for american citizens to visit France these days, that's pure demagogic propaganda... Of course, because we're friends, we discussed a little bit the State of the Union, and finally agreed on a scary point: for the moment, the Western World makes a big difference between the american administration and the american people. But if Bush is re-elected, and the last polls are quite bad for Kerry, the people here are going to say "hey, _they_ voted for him again and are happy with him!". Americans in Europe will not face danger, of course; but I'm sure they will face anger. And not only here in France. That will be the same in the whole continent, including the UK.
