LONDON/NEW YORK (Reuters) - If South Korea's Winter Olympics go off without a hitch this month, organisers will not be alone in toasting success. Their insurers will also be celebrating a tidy profit.

The Games are being staged about two hours' drive from one of the world's most heavily militarised borders, in a host country that is technically at war with its neighbour and with teams that include two nations -- the United States and North Korea -- which have swapped nuclear threats.
