What is with this post title?
Okay, of course every aggressive act has some form of excuse/justification that is given/believed by the aggressor. That doesn't mean that it was actually a valid justification. Of course it is important to look back to see what events and actions aided in creating the situation that allowed for aggressive acts to take place, but it doesn't change the fact that in many of these instances, including that in Ukraine is the aggressors fault, and is unjustified. The events following WW1 created a situation in Germany that allowed Fascism to thrive, and there were many decisions made by the West and the USSR that led to some of the atrocities in WW2, but that doesn't change the fact that the actions of Nazi Germany were unjustified and reprehensible.
A problem that I see is that a lot of replies and statements that immediately place blame on the West/NATO while glossing over the fact that the main contributor to the war in Ukraine is Russia. It is important to highlight that actions taken by the west played a part, but not without recognizing that Putin is the aggressor and is at fault for the invasion.
They have to distinguish between the Clippers and Lakers somehow.
