So the person that did it needs to be retrained.... seriously? How about get rid of the ENTIRE freaking department, his boss and anyone involved in this fiasco for being stupid, not paying attention, and worst - not even trying to retract it right now. The claim they did not know. In other words, lack of supervision, training and just who cares.
On a serious note, if there was a missile coming in from Korea, doesnt the United States have missiles and tech that can intercept them. With all of the tech Israel has been giving the US on this, I just can't believe they have not tested this out enough. (Iron Dome, Arrow)...
Tech should be spent on Patriots, THAAD defense or a better Aegis system
