NATO is showing no signs of getting involved militarily still.
Oh but they are 100 percent involved. They have been the ones telling Russia to go sit and spin for a week regarding Ukraine being allowed into Nato and the demands that the Baltic nations be removed from NATO so Russia has a buffer between NATO.
Russia is going to come after the Baltic states as well as Ukraine, you watch. They have only been training for it with Belarus for years under the Zapad exercises.
They will shoot for the land bridge between Belarus and Kaliningrad to cut them off , then invade from three fronts, the sea, Russia and Belarus with the forces in Kaliningrad holding the line and keeping any NATO forces from trying to come through the Baltic Sea or Poland with their missile units and forces from Belarus if necessary.
It will be near impossible to get the Russians out of the Baltic states without a Major air battle between Nato versus Russia and Belarus Probably the worst ever in history has ever witnessed. It would be started by our stealth assets and B-1s flying so low they will have salt spray and leaves hitting their windshields as they fire their cruise missiles destroying every SAM missile battery and ship in the region. Then going after Russias command and control relay stations to keep the orders from coming down the pipe will be key.
We will need to wipe out their fighter and bomber bases and definitely the 400 Russian backfire bombers in the first shots of the war if we are smart as they will be make the most damage to our ships and bases. The larger bombers are easy targets. The backfires are fast and good at low level cruise missile attacks against ships.
Only after we have destroyed their air assets can we run them back into Russia. It will not be easy at all and how much damage the Russians are willing to accept before they toss a battle field nuke is unknown. I think hitting their command and control sites will freak them out causing them to panic since they are a paranoid bunch.
I know this is likely to happen unless the west really starts standing up to Russia in a big way, to let them know in no certain terms that the Baltics will be fought for. Peace through strength is the only reason nothing happened in the Cold War. Today Russia sees America led by a bunch of fools. Telling Russia to piss off while not having the forces in place to stop them until they are sitting halfway through Poland or farther.
