The strategies involved in prosecuting the GWOT are sound. Some of the execution is flawed.
When you go to Kerry's website, and look at his National Defense bullet points, it's sad to note that what he is proposing is already being done by the current administration. His execution philosophies though, i'm sorry to say-are just plain wrong. He knows that, and will never use them, but he'll say that stuff now to get elected.
