We should all mourn those who died, but killing an old man isn't going to make them come back. It was 10 years and he wasn't even working with any terrorist. He shouldn't have been let go, he should have been captured.
Don't talk about lives being lost, how many troops and civilians in the middle east have lost their lives over the past 9 years due to the US?
Even better, if China bombed your town and killed your family, but our government refused to fight... what would you do?
