I agree, no taken life of a human is worth any change. Even if we could find a cure for cancer it would not justify eperiments with deadly outcome on humans.

But .. We need a powerfull democratic(!) country. Somebody has to play the world police. If nobody does that, we would be the pawn of countries like china. (We allready are in economics ... )

Somehow the USA are still a respected military force. And that is good.
Ok, I don't approve with the war in Iraque (or at least how it was done) Or with the many many civilian deads in Afghanistan.
