Fareed Zakaria addresses Afghanistan:
It will help immeasurably if we keep in mind the basic objective of U.S. policy there. "My own personal view is that our primary goal is to prevent Afghanistan from being used as a base for terrorists and extremists to attack the United States and its allies," said Secretary of Defense Robert Gates last week. That is an admirably clear statement.
It is not that we don’t have other goals—education, female literacy, centralized control of government services, drug eradication, liberal democracy. But many of them are objectives that will be realized over very long stretches of time, and should not be measured as part of military campaigns or political cycles. They are also goals that are not best achieved by military force. The U.S. Army is being asked to do enough as it is in Afghanistan. Helping it stay focused on a core mission is neither cramped nor defeatist. It is a realistic plan for success.
My sense is that this is exactly the minimalist objective Obama is aiming at. Anything more than the prevention of harm to the West is utopian.
