But you can not put a tzar bomb on a rocket, that can be fired from a silo or even from a submarine. And to threat America and Europe your rocket need to flight 10000 miles or more and reach Mach 5 or even faster. All possible only with high yield, compact warheads and advanced rocketry, which the Chinese do not have yet.
