Why should I readjust my moral compass? Because people could not forget their feuds and started to kill? The system held together by terror was pushed out of equilibrium. They had a change to find a better one but they chose not to. If anything then US has done not enough by letting sociopaths in Syria and Iran still run the show - a huge part of the deaths (I'm not going to dispute your claimed numbers) could have been averted and not only in Middle East.
Do you have a rule of thumb how many deaths you are willing to accept and risk on what probabilities for which futures? Also, you used the term sociopaths, do you consider yourself a psychopath?
It is clear now that Syrian leader was willing to murder hundreds of thousands of people, so were Iranian leaders. Moving against them early "could have" avoided large part of the Middle East casualties.
What perspective other then ideology has this not apply to your own position? You seemed pretty comfortable in your position despite the number of people killed and outcome counter to your declared intention.
