I think this is one of the reasons I stopped studying IR.
My heart couldn't take the analysis that my head was supplying.
Have you ever seen the movie "Rope"?
In that movie Jimmy Stuart plays a professor who has some interesting and ghastly ideas about class and society, which he casually teaches and tosses about in conversation. It isn't until the horrible human consequences of his thinking play a direct role in his life, and he can see firsthand the results of his teachings, that he is able to take a step back and realize what he had done (now, this is not much of a spoiler, and it's not the main plot of the movie, just something I think about from time to time).
So it is with me and IR policy. I can say that I believe giving in to terrorists demands causes more terrorism, but I can also say that I'm glad I didn't have to make the descision that gets someone's head cut off. Essentially letting a known one die to protect an unown many... I just don't have the stomach for it these days.
