"The situation here is very fluid right now and a lot of nerves are being frayed
because of the tensions between North and South Korea.
...New Mexico governor Bill Richardson is ...really worried that this situation is, in his words,
where one miscalculation could lead to all-out war.
He says he's never seen the situation so tense in all his visits to North Korea over the years;
he agrees it's the most serious crisis since the 1953 Armistice which ended the Korean War.
In my conversations with North Korean officials,
they insist it's all the fault of South Korea and the U.S.
They say they are being provoked and won't stand for it.
Clearly though, they are anxious to send a message...
...One event that's been added to Richardson's schedule Sunday
is a meeting with top North Korean military officials,
which is an important development.
...we are restricted on where we can go,
we don't have access to the internet or cell phones.
...It is bitter cold outside, lots of snow on the ground...
...you see people with shovels cleaning up the sidewalks, the streets,
it's a massive operation but they're doing it all by hand..."
