Surely, between:
- The Armenian Genocide
- The Holocaust
- The Holdomor
- Pogroms
- Apartheid regimes
- Purges of the Bourgeoisie
- One Child Policy
I find it hard to think that the US (With it's many, many fuck-ups) is the only, let alone the -worst- guilty party in the last 100 years.
O wait, if we only counted the last 100 years the 'great leap forward' would suddenly look a lot less great... wouldn't it?
