In a desperate and necessary move to get the deficit down many propose a complete and fast withdrawal from Afghanistan. It is a great proposal,we need to get out, but its affect on the deficit is not near enough to make a difference.
While it is not easy to get true costs of our evolvement there it appears to be about 200 billion dollars a year. It is a great start ,but keep in mind our deficit is close to one trillion dollars this year. The interest payments on our debt is 44o billion a year.
