It is always dangerous to underestimate what the North Koreans can and will do. Based on their
military actions agains us over the years since the cease fire agreement, sounds like they have gotten
the better of the US military and the South Koreans and did not have to pay a price for their aggression.
Flying an unarmed and unescorted recon plane, ship or whatever into harms way is foolhardy especially
when dealing with the ChiComs or the North Koreans.  They love catching the US with their pants down
so to speak so they can show their neighbors what a paper tiger the US really is.  So far, they have been
right every time.
