Europe would be almost wholly dependent on the US for defense against Russia. Just 3 or 4 years ago Germany had something like only ~10 fully operational fighter jets and literally ZERO operational submarines. The situation has improved slightly since then, but the military of most NATO members is puny. France and Britain are probably the only European nations that would provide any significant military force.
