North Korea conducted its longest-ever test flight of a ballistic missile Friday, sending an intermediate-range weapon hurtling over US ally Japan into the northern Pacific Ocean in a launch that signals both defiance of its rivals and a big technological advance.
Those options are "not only effective but overwhelming", Trump added for his part, after reviewing a military base near Washington.
Though they were not their top choices for the region, Haley and McMaster said, they were available to the President.
President Donald Trump honored the resolve of the nation's Air Force on Friday, warning foes and global terrorist groups that the US military would respond to any threats.
The top US officials said that it will take time to see how the latest round of U.N. Security Council resolutions might change North Korea's behavior, but that after these measures there's not much more that the diplomatic body can do to punish North Korea. "What we are seeing is they continue to be provocative, they continue to be reckless", Haley said. "As Ambassador Haley said before, we've been kicking the can down the road and we're out of road". "So, having said that, I have no problem with kicking it to [Defense Secretary James] Mattis because I think he has plenty of options". "Now it is not what we would prefer to do", McMaster said.
The sanctions were announced days before North Korea's latest provocation this week, the launching of a missile over Japan into the Pacific.
Earlier this week, the UN Security Council agreed to tighten sanctions on North Korea, banning its textile exports and capping fuel supplies.
