I sincerely question the intellect of those that join the military of the USA and Britain. I don’t trust these people and would not allow them in my inner circles. If they are not lacking intelligence they are lacking morality.
The people I don't trust are the ROTC lot. They had everything they needed to get into college, and then still decided their skillset was best applied committing atrocities. They're vastly more likely to be some jingoistic nut than the average highschool-to-bootcamp pipeliner.
