Lets see. North Korea blusters about sending nukes flying, then claims it has a right to nuke Japan if it downs a test missile.
So just exactly how it Japan to know if a missile is a test missile or the real thing?
Japan is in a no-win situation. A preemptive strike would thus seem justified.
A pre-emptive strike FROM ANY country against NK would be justifiable by now. In a sane world that is.
Apparently you can threaten your neighbors and the world with nuclear war, and get away with it. It’s like pointing a loaded gun at a cop and pulling back the hammer. At that point YOU DESERVE TO BE SHOT!
