The war is a result of tensions that were largely escalated by NATO, and plenty of experts in the west have been warning about this for many years now. Here's what Chomsky has to say on the subject:
50 prominent foreign policy experts (former senators, military officers, diplomats, etc.) sent an open letter to Clinton outlining their opposition to NATO expansion back in 1997:
George Kennan, arguably America's greatest ever foreign policy strategist, the architect of the U.S. cold war strategy warned that NATO expansion was a "tragic mistake" that ought to ultimately provoke a "bad reaction from Russia" back in 1998.
Jack F. Matlock Jr., US Ambassador to the Soviet Union from 1987-1991, warning in 1997 that NATO expansion was "the most profound strategic blunder, [encouraging] a chain of events that could produce the most serious security threat [...] since the Soviet Union collapsed"
Academics, such as John Mearsheimer and Jeffrey Sachs gave talks explaining why NATO actions would ultimately lead to conflict.
These and many other voices were marginalized, silenced, and ignored. Yet, now people such as yourself are trying to rewrite history and pretend that Russia attacked Ukraine out of the blue and completely unprovoked.
