note:

"Last week, U.S. Defense Intelligence Agency Director Lowell Jacoby testified on Capitol Hill that, according to a U.S. assessment, North Korea has the capacity to arm a missile with a nuclear device and hit U.S. territory.

Such a "two-stage" missile is "assessed to be within their capacity," Jacoby said in response to a question from Sen. Hillary Rodham Clinton, a New York Democrat.

The Pentagon later argued that Jacoby was not stating new information but only reiterating his previous statements that North Korea has a "theoretical capability to produce a warhead and mate it with a missile."
