Philip Coyle, a senior science adviser with the Center for Arms Control and Non-Proliferation, told science news Web site, Live Science, earlier on Tuesday that though Pyongyang does not yet have the capability needed to deploy nuclear missiles that can hit targets on U.S. soil, the North could soon become capable.
Coyle, who served as the director of operational tests and evaluation with the Pentagon, said that from the earliest uses in 1959 of the ICBM, the U.S. has been working on methods that would protect people from such an attack, including creating a shield or defense system. However, he said that efforts to come up with ways to fully intercept ICBMs have failed.
