media bias
Mostly I find that the Beeb is pretty fair in its reporting, but today's article on the Bush/Zapatero phone call was intially headlined, "Bush rebukes Spain for Iraq pull-out" before being somewhat toned down to "US chides...", if you could even call that toning down. Mostly there doesn't seem to be any direct indication that any rebuking or chiding took place, just that much-quoted line about giving the terrorists a false sense of comfort which, well, I don't see what's false about it.

Actually, there was a weird little snippet in one of those tapes that Bin Laden and his cronies (can't recall if it was ObL himself, alas) periodically release to Arabic TV stations (IIRC, this one came very shortly after the Madrid bombings), in which they mentioned that they hope Bush will win the next election. The argument went something along the lines of, "Bush is a militaristic idiot who will create many more Islamic extremists by ensuring that US troops kill lots of Muslims. Kerry, on the other hand, might be smart enough to cause problems for us."
Using the current Republican arguments, the conclusion is obvious.
