The current system being tested uses a kinetic kill vehicle, so it can't be made destructive at all. It's basically a big bullet moving really, really fast.
Now, other concepts have been bandied about for SDI over the years, including nuclear-tipped interceptors, or interceptors with nuke-powered "pump" x-ray lasers, but to my knowledge none of these concepts are currently on the drawing board.
To answer a point made previously about evading the system by either taking out the early-warning satellites or taking out the ground command station, neither of those is a serious threat.
1. As to the first, only a very sophisticated foe could mount a real anti-sat attack. The NMD program is not designed to stop an attack from such an aggressor, because their offensive systems will be too sophisticated for the limited defense contemplated by the Bush administration. Any country with the military and technical skills to mount a comprehensive anti-satellite effort are also able to overwhelm the defense. The Soviets (allegedly) had that capability, but I'm not sure they do now.
The Iraqis, by most accounts, were close to having a viable nuclear weapons program and ballistic missle program at the time of the gulf war. They aren't anywhere close to having the ability to shoot down a satellite in orbit.
2. As to the second, I don't know where the command center is projected to be, but you can bet it will have pretty decent security. You go try and take out NORAD or SAC headquarters tomorrow. See how far you get.
