The latest warnings from Pyongyang follow weeks of rising tensions, which promise to escalate further when the US and South Korea joint naval exercises begin Monday.
Equally, if Kim Jung-un were to attack South Korea or another American ally, the USA would destroy North Korea - and he knows it.
Two key officials in charge of North Korea's missile development were absent at recent major events, a mass rally in Pyongyang on Saturday and the Workers Party anniversary on Tuesday.
US President Donald Trump has not tweeted any threats to "Little Rocket Man" in response to Pyongyang's saber-rattling.
Not all the criticism for the situation is being layed on President Trump, though, as seventy-five percent of Americans also say that comments from the North Korea leader have been detrimental.
Ri told Russian state news agency TASS this week Trump has "lit the wick of war" against North Korea. But Trump has added to tensions in recent weeks by employing similarly tough talk, threatening to "totally destroy" or rain down "fire and fury" on North Korea. The nuclear-armed vessel offers the United States fleet "unprecedented strike and special operation mission capabilities from a stealthy, clandestine platform", a Pacific Fleet statement says, adding that it carries "tactical missiles", "superior communications capabilities" and provides assistance to special operation forces missions. "Let's hope that diplomacy works", the chief of staff said.
That has given rise to speculation that they are busy somewhere else preparing for a fresh missile launch.
It remains unclear whether North Korea will lash out with a weapons test during the exercise, as it often has in the past.
On Thursday, the United Arab Emirates said it would stop issuing new visas to North Korean workers.
By all indications, another North Korean provocation is inevitable - perhaps imminent.
