6. Pakistan
Pakistan continues to expand its nuclear arsenal with more warheads more delivery systems and a growing fissile materials production industry the pakistan now has a nuclear weapons stockpile of approximately 165 warheads with several new delivery systems in development four plutonium production reactors and an expanding uranium enrichment infrastructure pakistan's has the potential to increase further over the next 10 years the pakistan may become the world's third largest nuclear weapons stat with a stockpile of some 350 warheads a decade from now
5. United Kingdom
The united kingdom will raise its nuclear weapons stockpile by 40 while being prepared to use trident missiles against threats from emerging technologies or chemical and biological weapons it's estimated that the united kingdom have 215 warheads in their arsenal in total united kingdom's arsenal of nuclear warheads is expected to rise to 260 at a maximum cap and maximum missile range 12000 kilometers
