This is the business of Northern Europe and Russia.
It is not the business of the US.

Obviously if the goal of the Russians since the cold war has been to demolish NATO, if Russia succeeds in splitting Europe from the United States and forcing the withdrawal of NATO from all Baltic NATO allies, the result will be the fall of NATO and the isolation and eventual annihilation of the USA.
