When you say "A lot of Europeans," can you cite a source, like a poll or even an internet forum, where like-minded Europeans express this view?

I'm not challenging your assertion, I'd just like to see it in action and measure it for myself.

Edit: in case you edit or delete your post, this is what I'm asking about:

  Does still anyone believe that 9/11 was a terrorist
  attack. A lot of Europeans think it was the US
  government itself.

There is a Wikipedia article for everything: http://en.wikipedia.org/wiki/Opinion_polls_about_9/11_conspi... And specifically this international WorldPublicOpinion.org poll whose results are compiled there: http://upload.wikimedia.org/wikipedia/commons/2/2b/911worldo...

More or less, the opinion that the US government was behind the attack is clearly in the minority in all polled European countries.

Interesting to see the differences between countries here. That said,one has to be careful with polls in different countries: people's answers are very sensitive to question wording, and I imagine translations can introduce biases easily.

A lot of people believing something doesn't make it true.
