No. I don't think any of the allegences were, at the time, mistakes. You just do the best you can to handle each problem as it comes. If we hadn't allied with the Soviets against the Nazis, we might have lost WW2. If we hadn't done all we could to maintain stability in the free world to present a united front against the Soviets, perhaps the cold war might not have ended as it did. It's good to plan ahead, but if you concentrate too much on the road ahead, you may end up tripping on the bump right in front of you. I'm reminded of a little league playoff game in which my son's team was the underdog. I overheard the opposing coach bragging about how he was saving his good pitcher for the next game where he would face a better team. "That's strategy" he said. Well, he never made it to that next game. My son's team came out on top. Should the US have stayed away from unsavory characters and dictators in its fight with the Soviets to avoid problems with Moslem extremists once the Soviet Empire was destroyed? No way. The Soviet Empire was a real and immediate threat that had to be delt with. Otherwise, we might not have made it to the next game. In the real world there are always down sides. Celebrex is good for your arthritis, but bad for your heart. Airbags are good for adult males, but knock the heads off of children. Lipitor is good for your cholesterol, but bad for your liver. Moslem extreemists make good allies against godless commies, but tend to turn on you once the battle is won. That's life.
