Can the world live with a nuclear North Korea
? Yes, for a time. But not without significant danger. Despite the words of H.R. McMaster, President Donald Trump's national security adviser, North Korea
can be deterred -- at least at the nuclear level. Kim Jong Un is not suicidal. In fact, the need to survive and preserve his regime seems to be the primary impulse behind North Korea
's nuclear and missile programs. The American nuclear deterrent remains robust, and the addition of a North Korea
n nuclear capability is not likely to change that dynamic. Both Russia and China have maintained the ability to strike the United States
for decades, and nuclear deterrence has held. There is no reason to believe that North Korea
would be any different in this regard.
