BILL, GOOD MORNING. >> Reporter: GOOD MORNING,
SAVANNAH. GOOD MORNING, EVERYONE.
WE'VE ALL HAD THEM. MISUNDERSTANDINGS THAT LEAD TO
CONFLICT. BUT THE RISK OF THAT ON A GLOBAL
SCALE IS, PERHAPS, HIGHER AFTER NORTH KOREA'S CLAIM THAT THE
U.S. HAS DECLARED WAR. SOUTH KOREA WARNING THIS MORNING
OF AN ACCIDENTAL CLASH THAT COULD SPIRAL INTO NUCLEAR WAR.
A NEW NORTH KOREAN PROPAGANDA VIDEO.
A COMPUTER SIMULATION OF U.S. WARPLANES BEING DESTROYED.
AN AIRCRAFT CARRIER ON FIRE. THE CRUDE ILLUSTRATION OF A
THREAT FROM NORTH KOREA'S FOREIGN MINISTER.
SINCE THE U.S. DECLARED WAR ON OUR COUNTRY, WE HAVE A RIGHT TO
SHOOT DOWN ITS BOMBERS, EVEN WHEN THEY'RE OUTSIDE OUR AIR
SPACE. >> Reporter: U.S. B-1 BOMBERS
FLEW UNEXPECTEDLY CLOSE TO NORTH KOREA THIS LAST WEEKEND IN A
SHOW OF FORCE, JUST AS PRESIDENT TRUMP TWEETED THAT THE NORTH
KOREAN LEADERSHIP WON'T BE AROUND MUCH LONGER.
BUT THE WHITE HOUSE DENIES ANY OF THIS MEANS WAR.
>> WE'VE NOT DECLARED WAR ON NORTH KOREA.
FRANKLY, THE SUGGESTION OF THAT IS ABSURD.
>> Reporter: OVERNIGHT, THE AMERICAN DEFENSE SECRETARY IN
ASIA, TRYING TO CALM NERVES. >> THAT IS OUR GOAL TO SOLVE
THIS DIPLOMATICALLY. AND I BELIEVE THAT PRESIDENT
TRUMP HAS BEEN CLEAR ON THIS ISSUE.
>> ROCKET MAN -- >> Reporter: BUT THE RHETORIC,
THE PERSONAL THREATS AND INSULTS HAS THE WORLD WORRIED.
AT THE UNITED NATIONS. >> FIERY TALK CAN LEAD TO FATAL
MISUNDERSTANDINGS. >> Reporter: IN CHINA, WHICH
SAYS THIS IS GETTING DANGEROUS. NO ONE WOULD WIN A WAR.
AND IN SOUTH KOREA, CLAIMING THAT NORTH KOREA IS MOVING
WARPLANES TO NEW POSITIONS. THE TRIP WIRES ON THE PATH TO
POSSIBLE WAR ARE GROWING, AS MISSILES, WARPLANES AND THE
RISKS OF MISCALCULATION RISE. NOW, I SHOULD SAY NORTH KOREA
HAS ACCUSED THE U.S. OF DECLARING WAR AT LEAST THREE
TIMES BEFORE. BUT KIM JONG-UN SEES THIS
DISPUTE AS PERSONAL.
