US to shoot down dying satellite (Score 1)

Given the fact that shooting down a satellite will be a much greater challenge than shooting down an aircraft because of the broad range between the launch of the missile and the speed of the moving target-I am somewhat suprised that the missile isnt armed with a small nuclear warhead. The advantage of using a tiny nuclear warhead(no more than 5KT)would be that the satellite would pretty much be vaporized and there'd be no debree to worry about.
