Your idea of ‘containment’ in this sense means you’re defending the equivalent of a gang of serial rapists and murderers entering innocent people’s homes, taking their families hostage, and saying the home is now theirs.
Those who actually have read history books -- the kind not written by Dugin -- know this all too well.
Contain yourself.
I find it hard to understand people still use this argument with the straight face. NATO is not an entity that expands itself - individual countries, like Sweden or Finland, request to join it to protect themselves from the situation when Russia attacks them and they have to fight alone like Ukraine. Of course Putin hates that as he cannot fulfill his dream of expanding Russia to the borders of Soviet Union, but this argument doesn't stand any scrutiny.
