The United States can do nothing to stop North Korea from breaking international law in the next 10 days by firing a missile that is unlikely to be shot down by the U.S. or its allies, Defense Secretary Robert Gates said Sunday. Appearing on “FOX News Sunday,” Gates said North Korea “probably will” fire the missile, prompting host Chris Wallace to ask: “And there’s nothing we can do about it?” “No,” Gates answered, adding, “I would say we’re not prepared to do anything about it.”
