Donald Trump’s America First policy is “the height of American way of thinking that it is best if the U.S. is well-off at the expense of the whole world.” US allies and partners are “devoid of principle, narrow-minded and selfish.” The Trump administration is “trying to drive the world into a horrible nuclear disaster.”

These are the claims of North Korean diplomats in an open letter to various parliaments of the world. The letter, first published Oct. 20 by the Sydney Morning Herald, was called “unprecedented” by Australia’s top diplomat, Julie Bishop.

The communique is dated Sept. 28—10 days after the US president’s fiery speech to the UN General Assembly where he called North Korean leader Kim Jong Un “Rocket Man” and warned that if the US is “forced to defend itself or its allies, we will have no choice but to totally destroy North Korea.” It also comes on the heels of a fresh round of multi-national economic sanctions imposed in response to the country’s rocket tests over the summer.

Here’s the letter as published by Fairfax Media, the Sydney Morning Herald’s corporate parent.

It was sent via the North Korea embassy in Indonesia and marked received on Oct. 3.
