The corresponding information was reported by US Senator Lindsay Graham.
According to Graham, China should think about and take some action in connection with this.
He also stressed that the US president will not allow the DPRK to obtain an intercontinental ballistic missile that could contribute to a nuclear strike against the United States.
"If there is a war to stop Kim Jong-un, she will be there. If thousands die, they will die there. They will not die here.. Trump told me about it in person, "- added Graham.
Recall, as previously reported, "URA-Inform," US military found evidence of launching a missile from a submarine in North Korea. It is known that this was a test of the so-called "cold start system", in which the rocket is pushed into the air by high-pressure steam, after which its engine is already started.
