re: What Saddam did in his country was NONE of any other country's business
Saddam was using chemical weapons in 1985 (brought from the US) against Iraqis and Iranians and the US didn't move, because Iraq was the ally against Iran.
There is currently a huge amount of hypocrisy in the US about this.
Why is what Saddam did then, now considered genocide, and not then?
Far too often, the US shuts its eyes regarding human rights violations.
In fact, Bush Jr went to war against Iraq because of its dictator, that is ,because Saddam had been the US ally, once. And the conservatives couldn't stand being so much betrayed by its former ally.
It's mostly psychology.
Look what the consequences are from dealing with dictators.
Americans are dying for a lost cause.
