The head of the Pentagon is sure that pressure should be exerted on the DPRK in all possible ways. The variant with the use of physical and military force still remains in force, but the decision will be made by conscious governments and politicians.
Meatis supported the introduction of a new package of sanctions, but the main purpose of this pressure is to stop the North Korean government from developing and implementing its nuclear program. However, in 2017, despite the economic pressure, Pyongyang not only did not stop, but completed the development of a ballistic missile.
"I think you will see increased pressure," Mattis concludes..
As reported in "URA-Inform", US Secretary of Defense James Mattis is sure that Pyongyang's ballistic missiles can never reach Washington.
