Rodong Sinmun Sunday says this in an article.

A clear proof of it is the Korean War in the 1950s, the article notes, and goes on:

After igniting the war, the U.S. became all the more pronounced in plot-breeding to lay the blame for it at the door of the DPRK by abusing the name of the United Nations. And it made desperate efforts to militarily occupy the whole of Korea by mobilizing the huge aggression forces including one third of its ground force, one fifth of its air force and most of its Pacific Fleet, armies of 15 satellite countries, south Korean forces and Japanese militarists.

But the U.S. was seriously defeated for the first time in the history.

The U.S. is now vociferating about the non-existent "human rights issue" of the DPRK. This is aimed to stifle the DPRK at any cost by inciting the atmosphere against it in the international arena. The U.S. and its vassal forces are conducting base red herring by mobilizing criminals and imposters, who are hurling mud at the DPRK after selling everything of human being for a petty amount of money and fabricating their names and careers.

The U.S. has persistently denied the reality of the DPRK in a bid to prevent the deceptive nature of its false propaganda from being brought to light.

The article calls for remaining vigilant against the U.S. red herring and resolutely smash it.
