It's weird because it's a false narrative divorced from reality. It was NATO that continued expanding towards Russia until eventually Russia said enough is enough. NATO has been invading and destroying countries for decades since the end of USSR. Yugoslavia, Libya, and Syria are just a few examples of that. So, why would anybody expect Russia to tolerate an aggressive and hostile military alliance on its borders?

Furthermore, Russia tried to resolve this situation diplomatically since 2008 with Minsk agreements that western leaders now openly admit were a delaying tactic by the west.

Finally, section IX of Ukraine’s 1990 Declaration of State Sovereignty states the following:

The Ukrainian SSR solemnly declares its intention of becoming a permanently neutral state that does not participate in military blocs and adheres to three nuclear free principles: to accept, to produce and to purchase no nuclear weapons.

The whole legal basis for the existence of state of Ukraine is predicated on Ukraine staying neutral and not joining military blocs. Ukraine broke the very basis of this agreement when it tried to join NATO.
