Russia Ukraine war, page-56155

"Fourthly NATO, after the end of the cold war, has refused Russia's requests to become a member of NATO."


Russia NEVER made any formal requests to join NATO

Putin raised the issue during a meeting.....but no one knows whether he was serious or just trolling

or are you referring to Molotov's internal memo......?

which was really an attempt to separate the US from European NATO country and as such was really a proposal for a separate "alliance"
