So the US has dropped the biggest non-nuclear bomb ever on a group of murderous tribesmen in Afghanistan. We used to criticise CND for just opposing nuclear weapons, sometimes mocking them as the Campaign for Conventional Warfare. Logically, they should have no objection to America's action.
There is no logic in objecting to just some kinds of weapons. In fact there's no logic in objecting to war while not opposing capitalism, the cause of modern wars, over sources of raw materials, markets, trade routes and investment outlets and strategic points and areas to secure and protect them.
