|What do you think is the optimal size, in terms of explosive power, for strategic nuclear warheads?
Large warheads are prone to disadvantages such as large size and weight and increased fallout reaching friendly zones. Indeed, warheads above approximately 1Mt tend to have global atmospheric effects. Small warheads, on the other hand tend to be less stable and less durable and, of course, more of them are needed for large countervalue targets such as large cities.
If a country was to have only one type of strategic warhead and this was not to be a variable-yield warhead; what size of warheads should it procure and why?
