Let’s play a game:

I’m a nation that considers myself “the good guys” but I was built in the ethnic cleansing of one race, and built on the backs of slaves from another race.

I’m the only nation to have used nuclear weapons against civilians. Twice

I’m a multiracial nation with a massive prison population disproportionately made up of one race.

I tell people I’m invincible but I haven’t been on the winning side of a war since 1945.

I have the world’s largest economy while also having one of the largest national debts.

Which nation am I???
