US Secretary of Defense James Mattis commented on the DPRK's threats of a "super-powerful nuclear strike" at the United States, according to Reuters.
The Head of the Pentagon noted that the recent statements of North Korea were a provocation and in the past such threats were empty.
"As far as North Korea's latest words (are concerned), I think we've all come to hear their words repeatedly, their word has not proven honest," Mattis told a news conference in Tel Aviv.
On April 20, North Korean state media threatened the US with a "superpower preventive strike."
Earlier, at the night of April 16, tests of a ballistic missile failed in North Korea. The missile launch attempt was made the day after Pyongyang hosted a military parade dedicated to the 105th anniversary of the birth of DPRK founder Kim Il Sung. The ballistic missile (SLBM) of the Pukkuksong-2 submarine was first shown at the parade.
Previously, on April 14, the United States deployed two destroyers in the region that were firing Tomahawk missiles. One of them is 300 miles from the DPRK test range. Washington explained such actions by the need to ensure security in the region.
On April 20, the UN Security Council intended to pass a resolution on North Korea which was blocked by the Russian delegation.
