Your very long comment reveals that you understand the analogy but would rather complain about it than address it. Russia invaded Ukraine and is killing it’s people, correct? Digging deep into the geopolitical history to find some kind of reason is very much like apologizing for this murderer. It’s not an academic pursuit or a fun problem to study, it’s “I’ve got tanks and disposable people, I’m taking your land”.

When the schoolyard bully is on top of you, punching you in the face, it feels inappropriate to contemplate his bad childhood.

He (or you) ascribes alot of nuance and careful consideration to someone who has demonstrated nothing but malice and avarice. Putin clearly cares nothing for both the people of Ukraine and his own people. Why are we trying so hard to be understanding to a murderous dictator?

Seems to ignore the reason why Putin wants a non-NATO neighbor, namely so he can invade and control it.
