North Korea says it has put rockets on standby to strike at U.S. targets, including the American mainland. According to state-run media Leader Kim Jong Un is accusing Washington of reckless provocation. This latest threat comes after U.S. B-2 stealth bombers took part in military exercises in South Korea. Journalist Andrew Salmon wrote an article for CNN.com envisioning a hypothetical, worst-case scenario of potential conflict on the Korean peninsula: "Most of the wars we're fighting today are wars against terrorism, small wars, counterinsurgency wars. If we went to war with North Korea this would be a very, very big scale old-fashioned war of the worst kind of 20th century-style disruptiveness." The Obama administration wants to clean up the nation's air. Today the president proposed new rules on gasoline and auto emissions aimed at cutting down soot and smog. The oil industry warns the changes could mean higher prices at the pumps. But environmental groups insist the costs would be small - and worth it. Frank O’Donnell is president of Clean Air Watch: "This EPA plan would be the equivalent of taking 33 million cars off the roads in terms of its clean air benefits." World War II veteran Rene Joyeuse was a Swiss-born spy who worked for the U.S. Office of Strategic Services or OSS. His achievements were so great that General Dwight D. Eisenhower personally gave him the Distinguished Service Cross. When Joyeuse passed away last year a request for burial at Arlington National Cemetery was denied. But his son, Remi Joyeuse, says an effort to overturn that decision was successful and an urn containing the spy's cremated remains was buried at Arlington today: "It's about as big an honor as you could ever imagine. We're just blessed and thankful for all those that have put their time and effort to make this happen"
