It what was an apparent attempt at intimidation, a North Korean MIG-21 flew within 12-30 miles of the South Korean TAL (Tactical Action Line) and then returned to its base. The TAL is a virtual line designated by the South Korean military 12-30 miles north of the DMZ. If the line is crossed, South Korea will scramble its jets to challenge any intruder. Reports do not indicate whether the MIG-21 was challenged. This comes within 24 hours after North Korean leader Kim Jong-Un ordered his military leadership to put their rockets on standby to be launched against the U.S. mainland and U.S. bases in Guam, Japan and Hawaii. Photos showing Kim Jong-Un planning attacks against U.S. forces indicated Washington D.C. was also a target.
