Yeah it's pretty clear you're not trying to have a reasonable discussion when you mention that the USSR wanted to join NATO. That was an attempt to undermine the defensive pact by using it's own rules about inter-member conflicts against it.

One of the core strengths of NATO is that if a country is invaded then the other countries can't just vote to kick that state out. There is no mechanism to remove another country from the group, by design. So you are either uninformed or deliberately misrepresenting it when you discuss issues with certain members during their membership
