Colin Powell was the highest ranking US official I believe. I think he did it in a Congressional hearing.
China despite being the Second Largest Economy and Second Largest Land Mass of the 5 UN Security Council members has by far the least amount of Nuclear Weapons.
Estimates put China's Nuclear Weapons Arsenal at around 200. Compared to Russia's 10,000 and the U.S's 8,000. Are 200 Nukes more than enough, and Russia and the U.S are just simply wasting their money on a huge unneeded surplus of nukes, or does China require some more ?
