There are two ways of opposing a war with Iraq. The first way is simple and wrong; the second way is right but difficult....
The right way to oppose the war is to argue that the present system of containment and control is working and can be made to work better. This means that we should acknowledge the awfulness of the Iraqi regime and the dangers it poses, and then aim to deal with those dangers through coercive measures short of war. But this isn't a policy easy to defend, for we know exactly what coercive measures are necessary, and we also know how costly they are.
