By 2022, South Korea is expected to be spending more on defense than Japan and will rank as the fifth or sixth highest spender in the world on its defense. Military tensions on the Korean Peninsula are resulting in large sums being spent on defense, even though military experts often question the effectiveness of the Triad System. That system inevitably leads to South Korea purchasing advanced weapons from abroad -- mainly from the US -- which will profit the US defense industry while not being of much help to the South Korean defense industry and cutting-edge technology.
