The border between North and South Korea is the most heavily mined area in the world. South Korea is guarded from attack by the North with 35,000 US troops.

Most of the US border with Mexico is 4 strands of barbed wire.

I'd like to know how much it costs the US taxpayers to pay for the N-S Korean border. Why isn't that money being spent on our own border? There isn't much crossing going on from North to South Korea. The North Koreans take the path of least resistance into China by walking across a river that constitutes a border.

I've tried to search the Internet to find out how much it costs to house 35,000 American troops in S Korea and to maintain the border there with the North, but haven't found the numbers.

Does anyone out there know?
