Nato would cut Russian rai bridges over 100 miles inside Russia and Belarus using missiles and airpower, the Russian offensive would grind to a halt, Meanwhile NATO would bomb the shit out of Kaliningrad while the population inside the place revolted and the army mutinied. They wouldn't waste Troops trying to break through they would use air power and transport to support the Baltics and now so would Sweden and Finland. Poland would go through Belarus like shit through a goose via Ukraine with assistance from Ukraine.
If the Russians performed as they did in Ukraine against NATO it would be a turkey shoot. After this European strategy will focus on cutting rail bridges inside Russia and coming up with weapons systems that can kill masses of Russian troops remotely, drones and cluster munitions HIMARS and more. AA defense missiles like patriot and lasers are useful too and can apparently even stop some nuclear missile attacks, they stop the same kind of missiles in Ukraine and a modern EU system can do even better. America might want to look at missile defense again too, it is more likely to deal with a few missiles than thousands of warheads, Vlad has many enemies and not enough missiles to go around.
How Russia is Losing Kaliningrad (and why it matters)
In the shadow of Russia's war against Ukraine, there is a front that has often been forgotten.
The war is having a significant impact on Russia's exclave, Kaliningrad. And because of the consequences of Putin's invasion, the regions importance is quickly dwindling - to the point that Kaliningrad has lost its strategic value, and has become an expensive, and vulnerable area for Russia to manage.
