Those two statements directly conflict: Saddam kept things under control a lot better than the violent mess that exists in Iraq now.
There is a reason why Kurdistan is one of the most peaceful and developed regions in the Middle East: they act the way you must act to be a prosperous modern people. The violent radicals who squandered the post-Saddam opportunity to build a modern Iraq are to blame for the killing and the chaos.
John Bolton, is that you?
The Pax Americana is a widely recognized phenomenon.
Taking down democracy in Iran. Supporting dictators in Latin America and Africa and assisting them in hunting down democracy activists. Financing terrorism in Angola for two decades. Fabricating an incident in order to attack North Vietnam, killing 3 millions people. Supporting "Asian Hitler" Pol Pot and the Khmer Rouge. Tacitly supporting Pakistan's genocidal attack against Bangladesh. Selling weapons to the terrorist regime of Iran, and then using the money to support terrorists in central America. Fabricating a threat in order to invade Iraq (hundreds of thousands of dead, millions displaced). Supporting terrorist groups in Syria. Waging undeclared wars in (at least) seven countries at the moment.
"Small mistakes."
