SEOUL, South Korea (AP) — The United States flew two supersonic bombers over the Korean Peninsula on Sunday in a show of force against North Korea following the country's latest intercontinental ballistic missile test. The U.S. also said it conducted a successful test of a missile defense system located in Alaska.
The B-1 bombers were escorted by South Korean fighter jets as they performed a low-pass over an air base near the South Korean capital of Seoul before returning to Andersen Air Force Base in Guam, the U.S. Pacific Air Forces said in a statement.
It said the mission was a response to North Korea's two ICBM tests this month. Analysts say flight data from the North's second test, conducted Friday night, showed that a broader part of the mainland United States, including Los Angeles and Chicago, is now in range of Pyongyang's weapons.
Vice President Mike Pence said Sunday during a visit to Estonia that the U.S. and its allies plan to increase pressure on North Korea to end its nuclear program.
"The continued provocations by the rogue regime in North Korea are unacceptable and the United States of America is going to continue to marshal the support of nations across the region and across the world to further isolate North Korea economically and diplomatically," Pence said. "But the era of strategic patience is over. The president of the United States is leading a coalition of nations to bring pressure to bear until that time that North Korea will permanently abandon its nuclear and ballistic missile program."
"The time for talk is over," U.S. Ambassador to the United Nations Nikki Haley said in a statement. She denied reports that Washington would seek an emergency session of the U.N. Security Council, saying that new sanctions that fail to increase pressure would be "worse than nothing."
Haley said a weak resolution would show North Korean leader Kim Jong Un that "the international community is unwilling to challenge him," and singled out China, the North's biggest trading partner, as a country that must change its approach.
Japan's Prime Minister Shinzo Abe said he and President Donald Trump spoke by phone Monday morning Asia time and have agreed to take further action against North Korea. Abe said Trump pledged to "take all necessary measures to protect" Japan and that Abe praised his commitment to do so.
Abe said Japan would pursue concrete steps to bolster defense system and capabilities under the firm solidarity with the U.S. and do utmost to protect the safety of the Japanese people.
Gen. Terrence J. O'Shaughnessy, Pacific Air Forces commander, called North Korea "the most urgent threat to regional stability."
"Diplomacy remains the lead. However, we have a responsibility to our allies and our nation to showcase our unwavering commitment while planning for the worst-case scenario," O'Shaughnessy said. "If called upon, we are ready to respond with rapid, lethal, and overwhelming force at a time and place of our choosing."
Sen. Dianne Feinstein, a California Democrat, told CBS' "Face the Nation" that North Korea's latest test presents a clear and present danger to the United States.
"I've spent time on the intelligence and at the briefings, and done as much reading as I possibly could," said Feinstein, a member of the Senate Intelligence Committee. "And I'm convinced that North Korea has never moved at the speed that this leader has to develop an ICBM."
Feinstein said the situation shows the danger of isolating a country.
"I think the only solution is a diplomatic one," she said. "I'm very disappointed in China's response, that it has not been firmer or more helpful."
The United States often sends powerful warplanes in times of heightened tensions with North Korea. B-1 bombers have been sent to South Korea for flyovers several times this year in response to the North's banned missile tests, and also following the death of a U.S. college student last month after he was released by North Korea in a coma.
The Hwasong-14 ICBM, which the North first tested on July 4, is the highlight of several new weapons systems Pyongyang launched this year. They include an intermediate range missile that North Korea says is capable of hitting Alaska and Hawaii, and a solid-fuel midrange missile, which analysts say can be fired faster and more secretly than liquid-fuel missiles.
Gen. Lori Robinson, commander of the North American Aerospace Defense Command and U.S. Northern Command, responsible for homeland defense, said in a statement that the ICBM launched Friday "served as yet another reminder of North Korea's continued threat to the United States and our allies." She said the command "remains unwavering in our confidence that we can fully defend the United States against this ballistic missile threat."
The U.S. Missile Defense Agency said a Terminal High Altitude Area Defense, or THAAD, system located in Kodiak, Alaska, was successfully tested on Saturday night, Alaska time. It said that a medium-range ballistic missile was air-launched over the Pacific, and that the THAAD system detected, tracked and intercepted the target.
