But nobody said they were endorsed by the American public. The discussion is if the American actions were for a force of good, just because Americans were lied to by propaganda doesn't wipe away the actions. What do you think the people in the USSR thought (and knew about?)? Moreover, many of the US operations were not really secret, people either ignored them, or favoured them. Also you say crimes 70 years ago? The US implemented the largest mass surveillance system in the world very recently, strong-arming many allies and infiltrating the internet infrastructure of other allies as well as likely violating their own constitution in the process. Also note that the US has by far the largest proportion of their population incarcerated (although the unknown numbers on China's internment camps adding some uncertainty). Now nobody is saying China is better. The issue is that very often people (typical Americans) portrait the US as the main force of "good" in the world, but as soon as somebody points to all the atrocious things the US (the state not the people) have done, they get accused of anti-americanism, or people bring up "but China"
