Comment Re:Japan wants to shoot down NK missiles every tim (Score 2) 107
The policy has been to shoot down any missiles that had a trajectory indicating they could hit somewhere on land. Up until now no missile launch has really done that. There was one that came extremely close about last year and since then the discussion has been weather or not to start shooting them down reguardless of trajectory or broaden the "acceptable" limits and start shooting down missiles that look like they could come close.
The actual defense systems in place are some of the most advanced anti-missile defense systems available, save for perhaps Iron Dome in Israel.
