North Korea says war is a matter of when, not if

The U.S. flew a B-1B supersonic bomber over South Korea as part of a massive combined aerial exercise involving hundreds of warplanes — a clear warning after North Korea last week tested its biggest and most powerful missile yet.

"N. Korea says war is inevitable as allies continue war games," AP reports from Seoul: "In comments attributed to an unnamed Foreign Ministry spokesman ... North Korea says a nuclear war on the Korean Peninsula has become a matter of when, not if."
