Its worth noting, as well, that the general attitude of peace activists I met was tension and anger. They were impossible to reason with. This was because, on one hand, the sometimes considerable risks they took to oppose the war made them unable to accept the fact that their cause was not as noble as they believed. Then, too, their dogmatic anti-American attitudes naturally drew them to guides, translators, drivers and Iraqi acquaintances who were themselves supporters of the regime. These Iraqis, in turn, affected the peace activists until they came to share almost the same judgments and opinions as the terrorists and defenders of Saddam.

You can imagine how aghast I was when my French reporter friend told me that the Communist Party in his country actually considers the insurgents to be the equivalent of the French Gaullists!
