The Yanks can outspend Russia, out produce Russia, and have missiles that actually work (rather than dust everyone with atomic waste on test)
Given the size of Russia's economy (about the size of Spain's) and the success of Reagan's plan to outspend Gorbachev precipitating the collapse of the USSR, I would have thought that the best way of forcing Putin out of power would be for the US to ramp up military expenditure, forcing Putin and his cronies to follow suit until growing discontent from the increasingly impoverished populace finally caused him to be thrown out or to stand down?
