Re: Remember "Duck and Cover"?
China only needs a few ICBMs to offset the USA's. Not many.
They could build as many as they want, but they are so smart with the benefit of hindsight and history that they probably see it was the ICBM race that bankrupted the USSR.
Plus they already know the USA would never fire first on China, because we never fired first on the USSR, even though we could have, several times.
China already has the most powerful army and air force in Asia, more than enough to wipe the USA off the map there.
There is no incentive for China to waste its US dollars on ICBMs.
Think about it.
