North Korea, freed from the restraint it exhibited when Donald Trump was president, now has held a series of rallies across its landscape the mark a "day of struggle against U.S. imperialism" and promise to "annihilate the enemy."

The new threat to Americans comes even as there are red flags about the possibility of nuclear conflict breaking out because of the war between Russia and Ukraine.

The new threat was highlighted in a report by Fox News.

It explained the rallies were held in each North Korean province and leaders in the government over and over denounced the U.S. as "imperialist."

Those details are from the government-sponsored Korean Central News Agency, which claimed gatherings in Pyongyang totaled 120,000 people.

Slogans included, "The entire continental US is within our range!" and "The imperialist U.S. is the destroyer of peace."

There have been major concerns since the outbreak of the Russian invasion of Ukraine that nuclear weapons eventually could show up on the battlefield.

They rose higher when Vladimir Putin ordered the Russian military to put its forces, including those handling nukes, on "special alert" weeks ago.

Putin had warned that "whoever tries to hinder us" would see consequences "you have never seen in your history."

Media reported that was interpreted by many as signaling a threat to use nuclear armaments.

The degradation of relations with North Korea, which also has nukes, has developed under Joe Biden's watch in Washington.

WND reported that under President Trump, Americans detained in North Korea were returned to the U.S.

And there was a sort of summit, with Trump traveling to the border of North Korea.

According to Asia expert Gordon Chang, the author of "Nuclear Showdown: North Korea Takes on the World," Trump held the cards in the discussions.

He explained it was North Korea that was in need of sanctions relief, explaining U.S. and U.N. restrictions were "crimping the flow of money to North Korea, and, of course, Kim does not want the U.S. to strike both his missile and nuclear facilities."

He also suggested, at that time, Trump could use Russia and China for leverage against North Korea.

Chang explained there was progress under Trump because he took North Korea seriously.
