You should study some recent history. One place for you to start would be to look up "Appeasement" on wikipedia

It seems that someone has convinced many of you (on HN) that negotiations with Russia would inevitably lead to an attack on NATO countries within Europe. As a result, some now feel justified in mocking or harassing those who believe that continuing a seemingly unwinnable war—at the cost of thousands of European lives—is not the best course of action. Ironically, this stance was widely held by left-leaning individuals not long ago.

What disgusts me isn’t the fear of a potential Russian attack, but how easily people can be manipulated into reversing their beliefs while still considering themselves morally righteous, and feel justified into mocking and silencing people holding their past ideology.

People have had the time to learn what the "peace" they are offering to the victims of aggression means in practice.
