While keeping military-industrial complex is paramount, it is afterall just another tool. Frankly, these days, that Europe is blatantly showing unwillingness to protect its own borders and citizens against unwashed (but yet unarmed) hordes from south, I am more and more sure, that any conflict with Russia would end in absolute disaster for Euros. NATO is on paper far stronger, than either Russia or China in manpower and tech, but its leaders are so weak and corrupt, they wouldnt dare to use force against anyone but their own citizenry.
Post WW2 West devolved into late Roman empire.
