Why limit yourself to 50MT? An advanced and technologically supreme country like Pakistan should produce Gigatonne and Exatonne devices. The Soviets did 50MT almost half a century ago. Surely Bakistan, the formost of all nuclear armed countries can do better than 1 puny itsy-bitsy Megatonne!
We don't even need such huge yield to annihilate you from the map. On the other hand, yield is very important for you because your missiles are not accurate and even if they are accurate, a huge yield only gives away your lack of confidence in your missiles. Kiddo, if you are going to discuss nuclear bombs, by all means, discuss. But do so on the basis of facts not on the basis of bluster.
What do you mean by a 50MT bomb will destroy 50 cities? Are 50 cities ever clustered in a circle in the same region on earth? Do you know how much the weight of the bomb will be to yield 50MT? Check out the statistics of the Tsar Bomba. It was so massive that they had to modify a TU-22 to just carry one. Also, the delivery aircraft had to be specially painted to reflect the radiation, they had to employ a parachute to break the descent rate of the bomb so that the plane could escape the detonation. Even after all this, the aircraft narrowly escaped from being vapourised. If you were not such a numbskull, this discussion could have had more fruitful and informative progression.
