Every time US goes to war, such as against Iraq, Afghanistan, and so on, some "peace protesters" dominate the news by staging huge rallies, disrupt people's lives in general, raise a lot of ruckus all over the place. In the nutty place known as Berkeley California, there's even a protest right in front of an Armed Forces recruiting station. What exactly do they hope to accomplish with such actions?
It sounds like the protesters themselves don't even really know. If you ask them "how will your actions today stop the war and achieve peace?" Their answer is pretty much, "we need to show the government that fighting is not the answer!"
