I would also like to point out that the instruments of national power are four, not one: D (diplomatic), I (information), M (military), and E (economic). We cannot maintain the force you are talking about without destroying our economy. You have a myopic view of how to influence others, which in this case, should be easy enough to see. It is the economic power that Russia holds over Western Europe via the sale of cheap Natural Gas that will keep Russia safe, not their tank divisions.

Right now as we speak Zimbabweans are learning Mandarin, not English. Any guess why? So while we put our national budget into defense in order to keep the shipping ways free for world trade, those involved in world trade (like the Chinese) take advantage of our funding. We are losing not because we have a weaker military, but because we have no real economic influence to wield in comparison to others like Russia or China.

You need to update your thinking
