Trump declared war, claims North Korea. No he didn’t, says U.S.

North Korea’s top diplomat said Monday that U.S. President Donald Trump’s weekend tweet was a “declaration of war” and North Korea has the right to retaliate by shooting down U.S. bombers, even in international airspace.

It was the latest escalation in a week of undiplomatic exchanges between North Korea and the U.S. during the UN General Assembly’s annual ministerial meeting.

Foreign Minister Ri Yong Ho told reporters that the United Nations and the international community have said in recent days that they didn’t want “the war of words” to turn into “real action.”

But he said that by tweeting that North Korea’s leadership led by Kim Jong Un “won’t be around much longer,” Trump “declared the war on our country.”

Under the UN Charter, Ri said, North Korea has the right to self-defence and “every right” to take countermeasures, “including the right to shoot down the United States’ strategic bombers even when they’re not yet inside the airspace border of our country.”

Hours later, the White House pushed back on Ri’s claim, saying: “We have not declared war” on North Korea. The Trump administration, referring to Trump’s tweet, also clarified it is not seeking to overthrow North Korea’s government.

Trump tweeted on Saturday: “Just heard Foreign Minister of North Korea speak at UN. If he echoes thoughts of Little Rocket Man, they won’t be around much longer!” Trump also used the derisive “Rocket Man” reference to Kim in his speech to the UN General Assembly on Sept. 19, but this time he added the word “little.”

Trump’s national security adviser said North Korea must accept inspections of its nuclear facilities and declare it’s willing to give up its atomic weapons before the U.S. will negotiate with its government.

H.R. McMaster also said the Trump administration has gamed out “four to five” scenarios in which the North Korea nuclear threat is resolved. “Some are uglier than others,” he said in a speech hosted by the Institute for the Study of War on Monday.

“What we hope to do is avoid war, but we cannot discount that possibility,” McMaster said. He said it would be “unacceptable” for North Korea to achieve a ballistic missile tipped with a nuclear warhead, technology the country has not yet demonstrated.

This was not the first time North Korea has spoken about a declaration of war between the two countries. In July 2016, Pyongyang said U.S. sanctions imposed on Kim were “a declaration of war” against the Democratic People’s Republic of Korea and it made a similar statement after a new round of UN sanctions in December. The North Korean leader used the words again on Friday.
