North Korea missile could reach the U.S.

The latest ballistic missile fired by North Korea had sufficient range to reach Alaska, U.S. authorities said. A U.N. Security Council session was set for this afternoon.

WASHINGTON — The United States asserted Tuesday that North Korea’s latest missile launch was indeed an intercontinental ballistic missile, as the North had boasted and the U.S. and South Korea had feared. Secretary of State Rex Tillerson called it a “new escalation of the threat” to the U.S.

In a show of force directly responding to North Korea’s provocation, U.S. and South Korean soldiers fired “deep strike” precision missiles into South Korean territorial waters on Tuesday, U.S. military officials in Seoul said. The missile firings demonstrated U.S.-South Korean solidarity, the U.S. Eighth Army said in a statement.

At the request of the United States, Japan and South Korea, the United Nations Security Council was to hold an emergency session on Wednesday afternoon. Tillerson said that was part of a U.S. response that would include “stronger measures to hold the DPRK accountable,” using an acronym for the isolated nation’s formal name, the Democratic People’s Republic of Korea.

“Global action is required to stop a global threat,” Tillerson said. “Any country that hosts North Korean guest workers, provides any economic or military benefits, or fails to fully implement UN Security Council resolutions is aiding and abetting a dangerous regime.”

He said the United States “will never accept a nucleararmed North Korea.”

Tillerson’s statement, issued Tuesday evening as most Americans were celebrating the Fourth of July holiday, notably did not mention China, whose help the Trump administration has been aggressively seeking to press Pyongyang over its nuclear weapons program. In recent days, as the North has continued to test missiles in defiance of global pressure, President Donald Trump has started voicing doubt that Beijing is up to the task. His administration has taken a number of steps against China’s interests that have suggested its patience has run short.

Tillerson’s comments were the first public confirmation by the United States that the missile was an ICBM, constituting a major technological advancement for the North and its most successful missile test yet.

The prime danger from Washington’s viewpoint is the prospect of North Korea pairing a nuclear warhead with an ICBM. The latest U.S. intelligence assessment is that the North probably does not yet have that capability — putting a smallenough nuclear warhead atop an ICBM.

Initial U.S. military assessments said North Korea had tested an intermediate-range missile that landed in the Sea of Japan just under 600 linear miles from its launch point, Panghyon Airfield, near the Chinese border. The North American Aerospace Defense Command said the missile did not pose a threat to North America.

But government and independent analyses showed the missile traveling in a steep arc that topped out at more than 1,740 vertical miles above the Earth’s surface.

If flown in a more typical trajectory, the missile would have traveled about 4,100 miles, potentially putting all of Alaska within its range, according to former government officials and independent analysts. A missile that exceeds a range of 3,400 miles is classified as an ICBM.

Trump, in his initial response to the launch on Monday evening, urged China on Twitter to “put a heavy move on North Korea and end this nonsense once and for all!” But he also said it was “hard to believe” that South Korea and Japan, the two U.S. treaty allies most at risk from North Korea, would “put up with this much longer.”

Since he entered the White House, Trump has talked about confronting Pyongyang and pushing China to increase pressure on the North, but neither strategy has produced fast results. The White House has been threatening to move forward on its own, though administration officials have not settled on next steps.

Trump spoke with Chinese President Xi Jinping and Japanese Prime Minister Shinzo Abe on Monday, discussing North Korea and its nuclear program with both leaders. He will meet them both this week at the Group of 20 meeting in Germany, as well as have his first meeting with Russian President Vladimir Putin.

Trump and Xi emerged from their first meeting — in April at the U.S. president’s Florida estate — seemingly as fast friends. But China has long resisted intensifying economic pressure on neighboring North Korea, in part out of fear of the instability that could mount on its doorstep, and Trump has not found a way to break through Beijing’s old habits.

Trump has expressed frustration recently with North Korea’s nuclear ambitions, which have become one of his most vexing international problems.
