Russian bombers — what a joke. The local Key West Model Rocket Club could probably shoot them down. Maybe Putin could put some cavalry across from Alaska waiting for a good freeze to launch a mighty Russian attack across the Bering Strait.
It isn’t the aircraft you have to worry about, but the nuclear tipped air launched cruise missiles that they carry. They don’t have to go anywhere near U.S. airspace to launch them. Russia’s strategic bombers and their ALCMs are taken extremely seriously by U.S and NATO forces. Consider the reverse with USAF B-52s launching stand off ALCMs attacks against the Russian air defense system? Same problem and same headache for any air defense system. The Russians have the longest ranged ALCMs.
