Your argument doesn't hold water: You say, "If they can fly airplanes without pilots...." but those aircraft crash, as well. They also get hacked. You also say "slow ship." DDG's can do in excess of 20 knots- that's not "slow," especially for something carrying a helicopter and 40-something missiles on-board.  "modern ships?"  The McCain is over 25 years old-- so I am glad you support additional military and defense spending to ensure we remain the safe and dominant force we ought to be in that region. Here, here!
