Thanking US for stopping another dictator-sick-head. From your question and history of your comments I can presume that your empathies are with dictators and other scumbags. This is of course how it should be for a proper Russian propaganda. It's well established tradition of Russia to protect all sorts of scumbags and dictators. Also Russia started a WWII with their ally Hitler together attacking Poland.
Saddam got what he deserved, but the people of Iraq didn't deserved what came to them -- about half a million deaths[1] and later the rise of ISIS. Total number of people dead in the aftermath of American invasion is now bigger than the number of Saddams victims.
Do you know that the US supported Saddam in his war of agression against Iran? [0] Saddam could've been hanged much earlier and countless lives could've been saved if not for American support of scumbag and dictator.
As for WW2, please read about the Munich agreement.[2]
What were you doing when the US invaded Iraq in 2003?
