North Korea has an extensive tunnel network under the DMZ that will facilitate the circumvention of the largest minefield on Earth, if the North Koreans were ever stupid enough to attempt invasion (and there is nothing to suggest that they are going to). This fact demonstrates the uselessness of landmines – the world’s biggest minefield is militarily redundant, a danger only to those that will live in this area in future years. The USA knows this – the defence of South Korea is a hollow, false excuse offered in defence of landmines – the real reason is the unwillingness on the part of the military machine to relinquish the capability of any weapon, no matter how horrible. Of course, there is a healthy profit to be made in their distribution, too.
