Communist and dictatorial regimes have poor human rights records -- Stalin, Mao, Saddam Hussein; Tiananmen Square.
But do democracies fares much better?
Two invasions of the Middle East were conducted by the world's most powerful democracy, which went on to flagrantly violate the Geneva Convention on treatment of prisoners of war domestically and internationally.
The world's most populous democracy fares no better.
Even Hitler was, to a certain extent, democratically elected.
What does this portend? Perhaps that human rights violations will continue as long as large powerful central states exist, whether democratic or not.
