The Geneva conventions’ core protections to soldiers and civilians remain vital, but they do not address the continuum of conflicts that exist today. The Bush administration may be correct in asserting that the Geneva conventions in their present form cannot effectively serve their intended purpose.

I suspect that this is kind of a Rorshach-test article: folks who believe in the power of a system of international treaties and agreements to create processual protections that benefit everyone even as they limit state action will find it convincing. I'm not sure that those who believe that we are better off long-term acting independently in our own short-term interests irrespective of international opinion and procedure will find it convincing, though.
