unnecessary?
Tyrants rule through murder, torture, beatings, and threats. If no one is willing to die to fight them they win automatically. The only reason the world has become far more democratic in the last few hundred years is because of soldiers and civilian heros have been willing to die to take them out. A plurality if not most of these were Americans. You and many liberals demean their sacrifice by acting like the cause is worthless. This is really sad considering Hillary and Bill heros to many of these know better. They may disagree with Bush's methods, but not that the goal was worthy.
