The U.S. probably has even more advanced EMP weapons. When put into space they are a much more reliable anti-missile shield than the ground based trying to hit a bullet(rocket) with another bullet.
We are in an entirely new age of weaponry and I'm sure the military is just itching to try them out in Afghanistan.
Remember 'too stupid to quit' is a legitimate strategy.
How about reciprocal pinging on this topic? I suspect it will be of greater interest in the not too distant future. Sooner if the ragheads had anything to take out...
