3,000 lives lost when We Were Attacked, and we have made some radical adjustments to the concept of terrorism across the globe. It won't simply be dismissed, and these soldiers Went there to make a stand and say enough.
"IF" you are going to have a war, and War means people die, then This war is successful.
Everyone dies, these soldiers died believing in something. Personally, I'd prefer that route than dying of ignorance, or dying perfectly healthy but still going.
They are also over there, and at home, putting their lives on the line every day so that some of you maintain the Right to insult them and their cause. You should be proud, but They understand that They are willing to Fight and Die so you don't Have to be proud.
Things like this cannot be explained, not everyone wants or needs you to understand, it won't change what they are made of.
