For Such a "Great Country", Does Any Country Have a Nastier Past 200 Years Than the US?

Let us briefly count up the sins:
-- human slavery and racial segregation
-- the near extermination of native Americans
-- participation in and starting major and minor wars every few years, killing millions of people, gravely wounding millions more people
-- massive aerial bombardments, with conventional and incendiary bombs, killing untold numbers of people
-- the unprecedented nuking of hundreds of thousands of people in Hiroshima/Nagasaki
-- WWII Japanese internment camps
-- regular meddling in many other countries around the world, generating "low intensity conflicts" that kill hundreds of thousands
-- false flag terrorism, killing thousands of people and starting wars that led to more death
-- bioweapons/chemical weapons research and use
-- biological, psychological and radiation experiments on unsuspecting civilians and servicemen
-- torture and murder of "enemy combatants"
-- massive financial scams
-- excessive consumption, generating planet-damaging levels of pollution
-- constant propaganda, endless government lies

Let me know if I've missed anything.

The obvious retort here is Nazi Germany-- and clearly what the Germans did in WWII was horrific. But it's not clear that what they did over the long run was worse than what the US has done, and numbers-of-dead-people-wise, it may work out to about the same number. And the US breaks the tie with the nuking of the Japanese.

Note, I am not saying Americans are particularly evil-- that is, more than any other group of people-- and obviously Americans do lots of good things. But it is striking to tally up the truly horrible things that have been done in the name of the US-- and then contrast that with the constant propaganda put out by the elites here that the US is the greatest country in the world, or even in the history of the world!
