Also- we never "liberated" Afghanistan. We essentially bought off the warlords who hold the true power. Karzai and his puppet government have no power outside of Kabul.
As you stated, this joker is not representative if the US outside of the fact that he wears the uniform.
Those little village kids were born years after 9-11 occurred and yet were gunned down while they slept. At the very least, I hope being asleep meant they felt no pain nor sensed any fear of death, at any way, they are now spirits in Christ's hands as innocents killed, those little kids didn't do nothing to nobody, and deserved none of that. What is so freaking strange is that if this allegaged whacked out gunman had little kids of his own around the same age, shooting up these kids, it just does not fit. A lot of it does not make sense and is stomach turning in fact.
