Because you and I have extremely limited knowledge of geopolitics, of what's actually happening in Iran or the middle east. We have more than enough knowledge about life to know you don't kill babies because you think it will accrue to the greater good. When you don't know what you're talking about, best to wait for results before you evaluate. Iraq was a disaster, we can be pretty sure, years later. People were hyperventilating about taking Maduro in Venezuela, and that *might* turn out well. Iran might too. We don't know. The difference from an information perspective is vast. As I said, it's like getting worked up about a politician cheating on his wife -- you don't know them, their relationship, what preceded it, etc. You do know not to cheat on your own wife. If you were to distill it into a principle it would be this: You don't know all the consequences of ANYTHING you do. But when you act locally, you have enough specific knowledge to form intelligent heuristics and iterate. It's not perfect, but it works. That DOES NOT work or apply to low-information situations involving people you don't know engaged in geopolitics. For those, a wise person will wait for results before evaluating. It was obvious to me at the time that while I didn't know how this would turn out, and was deciding to wait, the hyperventilators also did not know either. The CNNs and the NYTimes were probably lying and framing things for political signaling, and most people were getting doctored information to fit their priors. I did believe Trump doesn't seem hellbent on killing civilians or getting us into a protracted military quagmire, based on his history as president, but I would never say he couldn't screw up, miscalculate or actually just be a psycho waiting for his chance. But while any of that was surely possible, I was pretty sure there WAS a plan, that plan was likely to track the incentives of the planners and those incentives probably were not WWIII, again with the possibility I was wrong. That's why I can't be for the intervention until we find out more. If you want to be a good evaluator of information in the information age, you need to adjust your certainty levels based on what you know and don't know, not based on whether it confirms your biases.
