Why would you ask a question like that unless you're being a dick trying to purposefully misrepresent my opinion on these matters. Russia before the war was demographically in an irreversible death spiral within a generation much like Ukraine is. Europe is in a death spiral as a whole.
Let me remind you that the West promised not to expand NATO. Let me remind you that the 2014 revolt by Nazis in Ukraine (called the Maidan Revolution) overthrew a duly elected ally to Russia. Let me remind you that even though Putin is a monster so were Saddam and Gaddafy. Their removal of the devil you know made it worse for Iraq and Libya at least in the short term. But then neither of those two actually had WMD's. Your juvenile gung ho attitude is great for cannon fodder when you need to feed cannon fodder their righteous propaganda to screw up their courage and determination.
Feel free to provide a link to where "the west" promised not to expand NATO
In fact...how was it that Yanukovych was "overthrown"? He was voted out by the parliament.
We were wrong to invade Iraq. I have posted that a number of times. "W" claimed Saddam was about to supply WMD to terrorists and was building a nuclear weapon. He lied.
The people of Libya rose up against Gaddafi. His mercenaries were slaughtering the rebels. We helped suppress his airforce and armor. Should we have stayed out?
