Let me give it a go! Switzerland basically bankrolled the Nazi war machine. Without Switzerland, Germany would have been unable to stash away all of the treasures it stole and likely wouldn't have been able to carry out the Holocaust with the efficiency it did.[1] Pretty bad huh?
New Zealand has a dismal record on aboriginal rights. The Maori make up 4% of the population, but 50% of the prison population. Check out Amnesty International if you want to read up on other stuff. Some have labelled it genocide.
what you'd dig up on the US would still be far, far, far, far worse
That's purely subjective and I'm sure you'd find many who would disagree.
I'm not arguing that the US shouldn't be criticized. What I'm arguing about is the utter shock that people display when they find out the US hasn't been perfect. It almost seems like the US is held to a much higher standard than other Western nations.
