Putin demanding from the US - which runs NATO - a written, legally binding guarantee that the alliance will not advance further eastward towards Russian borders is the game-changer here.
Team Biden cannot possibly deliver: they would be eaten alive by the War Inc establishment. Putin studied his history and knows that Daddy Bush's "promise" to Gorbachev on NATO expansion was just a lie. He knows those who run NATO will never commit themselves in writing.
So that allows Putin a full range of options to defend Russian national security. "Invasion" is a joke; Ukraine, rotting from the inside, consumed by fear, loathing and poverty, will remain in limbo, while Donetsk and Lugansk will be progressively interconnected with the Russian Federation.
There will be no NATO war on Russia - as Martyanov himself has extensively demonstrated NATO wouldn't last five minutes against Russian hypersonic weapons. And Moscow will be focused on what really matters geoeconomically and geopolitically: solidifying the Eurasia Economic Union (EAEU) and the Greater Eurasia Partnership.
