North Korea successfully launched a missile this past weekend and now the U.S. has tested its ability to intercept missiles.

FOX's Jessica Rosenthal reports, the test was successful:

An interceptor was launched shortly before 1 pm Pacific time out of California's Vandenberg Air Force Base and according to the Pentagon, it took out the ICBM they launched from the Marshall Islands. While the Ground Based missile defense system has been tested before:

(Pollack) "This is the first one that will be an ICBM class target, that is to say a missile with the capabilities of an intercontinental ballistic missile like the one that would come out of North Korea."

Joshua Pollack, editor of the Non Proliferation Review, says he's generally lacked confidence in this system; he says it's been too expensive, not extensively tested and has experienced technical problems.
