Isn't there a natural limit to the maximum yield of a nuclear bomb, where water gets involved in the reaction the surface of the whole planet gets wiped clean? At least that's what they feared in 1960s, the idea was proposed by a famous physicist (Nils Bore, IIRC... or Teller... or Openheimer) decades earlier, Soviets recalled it during Tsar bomba explosion, since the reaction lasted longer than expected, and they went like "oh, shit, what if..?!" So after that calculations were done, and yes, seemed like it's possible and they are already capable if making such a doomsday device. HOWEVER, recently I've heard it's either just a myth, or such scenario is impossible since there isn't enough heavy water in oceans.
