No we couldn't. The German armed forces are literally shambles and can basiclly be ignored for the most part . UK, Germany and France combined dont even have half the number of battle ranks Russia has even if most of them are dated. If Russia just blitz'd through half of eastern Europe there would basiclly be 0 resistance. Air power doesnt matter when Russia poses the most high tech anti air equipment. None of the major powers in Europe are ready for a war, the UK cant even get enough recruits to fulfill its requirements. If the powers in Europe focused on proper rearmament we could easily be ready and able but as of right now we arent even close without America.
