This is a re-post of something I wrote for the Lowy Institute earlier this month. The original is here.
So yes, Donald Trump is awful. He is a threat to American democracy, an vain narcissist, doesn’t know anything about nuclear weapons or national security, and so on. I know what you’re thinking, so I will say that I mailed-in my absentee ballot today, and I voted for Hillary Clinton.
That does not necessarily impugn all of his ideas however. And when he says that Japan and South Korea might pursue their own nuclear weapons, I have never understood the hysteria that greets this notion. That Trump says it, and that he might not really even understand what he’s saying, does not automatically mean it is wrong.
The debate over SK and Japanese nuclearization is a lot more variegated that we normally hear from mostly ‘liberal international order’ analysts who dominate Washington thinking on foreign policy. The essay below makes several claims, but the strongest to my mind is that a northeast Asian nuclear arms race is already underway; SK and Japan are just not participating in it – which does not mean it is not happening. It is true that they need not to some extent, because they are covered by American extended deterrence, which gives them ‘shadow nuclear weapons’ I suppose.
But the costs of them going nuclear are not that high anymore. Russia and North Korea have both substantially elevated the role of nuclear weapons in their grand strategies in the last two decades. China might start counter-building, but what is China doing for Japan or South Korea that it earns the privilege of them staying non-nuclear? Specifically, if China won’t rein in NK, the case for SK and Japanese nuclear restraint diminishes.
The full essay follows the jump.
