This is pure wishful thinking. For seventy years the US has a unrealistic paternalistic policy on nuclear proliferation which basically said we are not going to tolerate any other country developing nukes...but once they did our reaction has been in the words of that noted diplomat Emily Litella... "Never mind"....
The US thinking we have a right or ability, short of war, to prevent any nation from having nukes if foolhardy. Seems to me the thinking needs to shift to the prevention of the use of nukes by the nations that acquire them....
