I agree. After 9/11, we can't have a WOT against an enemy that is bent on using WMD against us and have no control over our borders. The BP nabs a million a year and another 500,000 get through. They are not just Mexicans, but many other nationalities, including some from the Middle East.
You can bet that if we have a dirty bomb go off in an American city or a biological attack, the borders will be closed like the barn door after the horse got out.
