We should not be footing the bill for this trip.
Who should?
I think it’s reasonable to consider footing the bill if only for the reason that these guys had their own transportation arranged but it crapped out on the last leg of the trip. They’re not asking for a ride from the States, they’re in Okinawa for pete’s sake. If the Commandant of the Marine Corps is coming you can bet that there is a shitpot of support going too. No reason these guys can’t be slipped on Space “A” somewhere.
