20 years ago, the President was running a war that was justified by shady supposed intelligence about the enemy having weapons of mass destruction, and was authorizing foreign prisoners to be sent to be tortured in secret sites in Eastern Europe.

50 years ago, the President was supporting numerous brutal authoritarian third-world regimes that routinely used torture and murder. That still happens, but it happened more during the Cold War.

US foreign policy is actually a lot more moral now than it was during the Cold War. I think this probably has more to do with how much harder it is to hide things from the masses than it does with a change of heart, but the fact remains.
