The west has been pouring billions into the military industry over the past three years and still isn't able to meaningfully ramp up production right now. Simply pouring money into this isn't the solution, it would take a lot of structural changes to create a functional military industry. Meanwhile, Europe is now in deep economic trouble, and diverting large parts of the budget towards military will only make domestic unrest grow as it will result in further austerity. Political stability is by far the biggest near term problem for the EU.
