The assumption that the issues are always what the antiwar people say they are.

The issue isn't casualties. It isn't Iraq, terrorism, national security, or weapons of mass destruction. For a lot of the antiwar people, the issue is one single element: the political destruction of George W. Bush. For a certain few of them, it's raw anti-Americanism and anti-Westernism. If it wasn't Iraq, it would be something else. This is just the only straw they have to cling to right now.

You can pretty much tell after a while of listening to a particular antiwar individual what his real motivations are. Democratic politicians in particular.
