WASHINGTON (AP) - U.S. defenses could intercept a ballistic missile launched by North Korea, the top U.S. military commander in the Pacific said Tuesday as the relationship between the West and the communist government hit its lowest point since the end of the Korean War.
Adm. Samuel Locklear, commander of U.S. Pacific Command, told the Senate Armed Services Committee that Kim Jong Un, the country's young and still relatively untested new leader, has used the past year to consolidate his power.
The admiral said Pyongyang's pursuit of nuclear weapons and long-range ballistic missiles represents a clear threat to the United States and its allies in the region.
During an exchange with Sen. John McCain, R-Ariz., Locklear said the U.S. military has the capability to thwart a North Korean strike, but he said a decision on whether a missile should be intercepted should be based on where it is aimed and expected to land.
"I believe we have the ability to defend the homeland, Guam, Hawaii and defend our allies," said Locklear, who added that it wouldn't take long to determine where a missile would strike.
Locklear concurred with McCain's assessment that the tension between North Korea and the West was the worst since the end of the Korean War in the early 1950s. But the admiral insisted that the U.S. military and its allies would be ready if North Korea tried to strike.
He said North Korea is keeping a large percentage of its combat forces along the demilitarized zone with South Korea, a position that allows the North to threaten U.S. and South Korean civilian and military personnel.
Locklear told the panel, "The continued advancement of the North's nuclear and missile programs, its conventional force posture and its willingness to resort to asymmetric actions as a tool of coercive diplomacy creates an environment marked by the potential for miscalculation. ..."
Increasingly bellicose rhetoric has come from Pyongyang and its leader, with North Korea urging foreign companies and tourists to leave South Korea and warning that the countries are on the verge of a nuclear war.
Senate Armed Services Committee Chairman Carl Levin, D-Mich., told Locklear that the North Korean government's threats "appear to exceed its capabilities, and its use of what capabilities it has against the U.S. or our allies seems highly unlikely and would be completely contrary to the regime's primary goal of survival."
"Nonetheless, its words and actions are not without consequences," Levin said.
The Democrat did question the Obama administration's decision to delay a long-scheduled operational test of an intercontinental ballistic missile amid the North Korea rhetoric.
Locklear said he agreed with the decision to delay the test.
"We have demonstrated to the people of the region, demonstrated to the leadership of North Korea, our ability and willingness to defend our nation, our people, our allies and our forward deployed forces," Locklear said, citing other steps the U.S. military has taken in recent weeks.
The U.S. has moved 2 of the Navy's missile-defense ships closer to the Korean peninsula, and a land-based system is being deployed to the Pacific territory of Guam. The U.S. also called attention to the annual U.S.-South Korean military exercise that included a practice run over South Korea by B-2 stealth bombers.
Levin mentioned that President Barack Obama recently talked to China's new president, Xi Jinping, about the U.S. efforts to deal with North Korea. Locklear said he has not had similar conversations with his Chinese counterparts.
The scope of Locklear's responsibilities as the top officer at Pacific Command extend beyond the Korean peninsula, and he told the committee that his command is closely watching the proliferation of submarines among countries including China and Vietnam. Locklear said there are an estimated 300 submarines in the Pacific region, although he noted that no country there has an undersea force as capable as the United States'.
Both Russia and China are expected soon to deploy new ballistic missile submarines capable of threatening the United States, Locklear said. India is also expanding its submarine force, and Australia, Singapore, Indonesia, Malaysia, Vietnam, and South Korea have launched, or soon will, modern submarines.
