Did Kim Jong Un just bury Trump's nuclear diplomacy?

Addressing North Korean veterans on Monday, Kim Jong Un appeared to draw a line under his nuclear weapons diplomacy with President Trump.

Kim did so by suggesting that his nuclear weapons program is no longer up for negotiation. As the Workers Party of Korea chairman put it, “War is an armed clash, which can be unleashed only against a weak one. None can now make little of us. We will not allow others to look down upon us, and, if they do so, make them pay dearly. Thanks to our reliable and effective self-defense nuclear deterrence, the word ‘war’ would no longer exist on this land, and the security and future of our state will be guaranteed forever.”
