Yeah, it's good to bring up incidents to get people all fired up. Should we also bring up all of the other atrocities that happened by one countries' citizens to another? What about all the atrocities that happen every day by one countries' citizens to their own citizens?
Humans can and do amazingly horrible acts both in war and out. Do we change foreign policy drastically because of one act of craziness by a group of crazy individuals? I guess that's the question.
Do you change the way you vote because one religious radical commits a horrendous crime against nature? If so, does that not give them more power (like what happened in Spain - bomb a train, change the elections).
Not that I'm for having American bases all over the world at a cost that’s so high it's crushing our own financial health. I’m against it. However, If countries drastically change their course because of isolated craziness we are all in for a wild ride.
The best we can do is work together, make agreements, work on our relationships between nations and try as hard as we can to keep things stable. Will there be conflicts? Of course. It’s human nature. Can those conflicts be contained so they don't lead to world war? They must be contained.
I think the world learned a good lesson over the past 8 years. We don't want to have foreign policy like that. Harsh, isolating, filled with conflict and suspicion, dogmatic and self righteous. Dropping bombs at a moment's notice.
