North Korea is shaking up the way it handles relations with South Korea, enacting changes to policy and government organizations that would effectively treat the South as a separate, enemy state.

The moves, which break with decades of policy, could have North Korea¡¯s foreign ministry taking over relations with the South, and potentially help justify the use of nuclear weapons against Seoul in a future war, analysts said.

Since the 1950-53 Korean War ended in a stalemate, both nations have had policies that treat each other differently than other countries.
