It's of course terrible. Not because of the whole arresting people without trial. Without a doubt that is terrible. But it in no way affects as many innocent and peaceful people as our current desire to intervene in the affairs of other people. Wherever we go, wherever we fight, we only bring pain and suffering to innocent people. It's high time we've STOPPED these wars and gotten out of the business of violating the sovereignty of other nations. If nations wish to live like animals I am perfectly inclined to let them.
And don't say "Well, if the US doesn't project its power onto the world, people will surely aggress against us. We need to show we are strong." that is an incredibly weak argument. No one believes we are weak. I'm almost certain we have enough nuclear weapons (we have 5000) to kill 99% of the world's population, probably numerous times over.
No one is going to attack us if we do not give them provocation.
