I used to be a serious person because it was easy. I would fret and assume my thinking about a political question mattered, so when the public domain stirred up about foreign policy I would read people I assumed to reflect a reasoned and thoughtful logical position from each side (again, an assumption of 'two' points of view) and then agonize about determining which position could be right.
For instance I was torn about events in the world after the terrorist attack of 9/11. Of course we should hunt down the perpetrators and send a million guys with guns into Afghanistan once we determined (we is not me, but my elected and appointed government officials-even if I didn't vote for them) who was guilty as to all the evidence we could gather. I assume the best about someone in our government, which is no longer a feature but a bug in my personal operating system.
Iraq was a much tougher personal call to make, but with Saddam, 'anything but' seemed a reasonable alternative. Once it came out that we were torturing our prisoners this worm turned, but sometimes good comes from ill. My optimism rests on the solid ground of post event rationalization, like going to Mexican restaurant when I'm on a diet .
But now, I'm not reasonable about our foreign affairs, I'm reflexively and permanently in the 'NO' category. The right choice about Libya, or the right choices about Ukrainistan or anywhere else just can't involve our 'strength' and 'resolve' anymore. The endless impulse to 'do something' about 'bad guys' and helping people by helping them dismantle every public infrastructure with bombs. Suppose whenever we think we have picked the good guys in a country we did everything but send them guns? And if they insist on killing each other, well, go right ahead, America had its 'been there done that' moment in the 1860s. We still pay for it, especially if you aren't white.
My impulse isn't just "NO", I'm firmly in the "HELL FUCKING NO" camp now. Let other countries rationalize deaths and destruction as progress, allow other political scientists from other countries determine how to have conversations grounded in reality with religious and political movements which are only understandable in the context of assuming human knowledge ceased in 1000 AD.
Americans should be done with developing functional, just, societies by sending men with guns and if we look at our own history, we should be a little more humble. We stopped killing each other in the 1860's, except for sport.
