"At the end of the day, aren't those of us that aren't there left to blindly trust that the "right" people are being killed for the "right" reasons?"
Unfortunately, yes, because you can be sure that, in the fog of war, a lot of the wrong people are going to get killed to get at the "right" people. Call it collateral damage or whatever, it is inevitable. And then there are those troubling incidents like the firebombing of Tokyo and Dresden, or carpet bombing in Vietnam, where a lot of the wrong people were killed in cold blood. Hiroshima or Nagasaki? Best not go there. For the "right" reasons? Lest I be accused of being anti US, it is also worth mentioning Nazi Germany's behavior nearly everywhere they went, the Japanese Army's behavior in China, Burma, Malaysia, the Soviet Union in Afghanistan. Every bit as barbaric, perhaps more so. My point is that it is best to think long and hard before drawing the sword, because once it is out of the scabbard, the red shades come down, and there will be blood, lots of it, most of it that of the innocent. The only real distinction that I make between my own country and the rest of the developed world is that we seem to stand alone in being almost continually engaged in a war somewhere abroad, with all the predictable consequences, beginning with Vietnam. The sole exception I can think of is the Soviets in Afghanistan. I find that deeply troubing, and ascribe it in considerable measure to "blind trust" that the populations of those countries who have experienced the terrible destruction of war up close and personal no longer accord to their leaders. They have finally learned the hard lessons that we have yet to face. I hope we learn them without paying the same terrible price.
