Marches like this have been taking place throughout the course of the war, and even before the war started. The one I attended in 2005 in Washington, when Cindy Sheehan's controversy was in full swing (this was following Bush's summer vacation), was about three times as large as this one.

It seems as if the media is only now covering these things as if it were a new phenomena. Thereby creating an illusion that strong opposition and protest to this war is something rather recent. Also creating an illusion that somehow this war and this president was protested less than Vietnam and LBJ. In actuality the opposite is true. The war in Iraq has had a level of protest at an unprecedented level (and worldwide marches protesting the war before it happened was also unprecedented).

The media in the 60's mostly reported the news. Now the media today reports what's popular.

And what might you suggest this "something" be?

Perhaps something along the lines of what our government did to 'unwanted' protesters and political organizers of the 60's? Arresting, deporting, spying, stalking, and assassinating?
