In light of disintegration of Ukraine and the presence of US-supported Nazi groups at Europe’s borders, the Europeans might accelerate the creation of their own army. Russia may use this opportunity to join the EU army. In the past Russia requested to join NATO, but it was refused.
No evidence given. Recurring pro-Kremlin narrative about the creation of an European army, also as an alternative to NATO.
No record of any official request from Russia to join NATO can be found. According to NATO, it has worked to build a partnership with Russia, developing "dialogue and practical cooperation in areas of common interest". Cooperation has been suspended since 2014, in response to Russia’s military intervention in Ukraine but political and military channels of communication remain open.
