> The nation isn't perfect, but does anyone really believe that, on net, America hasn't been a force for good in the world? What is your benchmark?

Lots of people all over the world who have been on the receiving end of US military or economic aggression enacted in the interests of the US plutocrats.

African Americans, Native Americans, most of South America, pretty much all of the Middle East and North Africa, anyone who has suffered structural violence as a result of the US's insistence on a morally bankrupt Friedman hack-job neoliberal economic ideology.

The US has done a lot of good things, but on balance I think it's done more damage and has merely replaced the British Empire as the current Anglo-sphere imperialist power.
