To me this sounds like a military industrial complex propaganda piece. First off the greatest threat to America is the fool who shows up at the White House five days a week. Trump working with Putin trumps any increase in military hardware.
Moreover, nuclear weapons have long precluded any all-out, direct war between major powers short of total annihilation of humanity.
And finally the ultimate law of the universe, probability balance (stars are born and stars die as all creation at some point in time must be offset by destruction), dictates that man’s creations must soon be offset by total destruction. In other words the likelihood of some political miscalculation or technical glitch among the ever spreading nuclear devices to incinerate the globe is through the roof. Thus massive, super expensive conventional weapons are a waste of money.
