LOL! The people of Crimea and Donbas did not rise up against the government of Ukraine; Russian operatives seized the territories militarily. Nor did the alleged attacks on civilians happen in Donbas. In the first place, Russia seized Crimea before hostilities broke out in Donbas. Secondly, the Russian seizure of Donbas happened too quickly for there to have been the pattern of attacks alleged. Admit the reality, Russia took advantage of the events in 2014 to seize territories that it had long coveted. Now Russia is trying to take more territory and subjugate the entirety of Ukraine. The truth is that this is all the war is about.
Oh, really?
You mean none of the following had an impact on the Ruskie decision.....
-US/NATO broken promise NOT to expand at the USSR breakup in return for giving up East Germany
-the US/NATO invasion of a sovereign country with a democratically elected government in the coup of 2014
-the broken promise of several European nations to follow the Minsk accords -- and subsequent admission it was all a delaying tactic only (in other words -- a big lie)
-Putin's written offer to resolve the matter by diplomacy before the first tank rolled into Ukieland -- which was summarily refused without a counter
-US/NATO announced plan to regime change and break up Russia
Oh, sure. All the Ruskies wanted was the land. Exactly how much land did the Ruskies invade and capture from the time of the USSR breakup until 2014?
Or better yet, how many countries did the US/NATO invade in the same time period? And exactly WHO are the invaders??
Finally, it is noted you did not address the question of what would happen if the Chinese regime changed Mexico and placed missiles in Tijuana. 'Cause that's exactly what Putin is doing to protect his country.
