Can you just imagine the American lawyers hands rubbing together with pure glee when this contract was signed? They must have been thinking "surely we'll get caught before this goes through ... surely someone with some sense will twig to this before it becomes official ... surely they aren't THIS stupid ... but boy oh boy are we gonna CLEAN UP!".
Oh and then they probably offered the MoD idiots a bridge in Brooklyn after the contract was signed ("You can have it for the price of repainting it").
... but nobody twigged, they didn't get caught, the contract went through, MoD really are that stupid, and they ARE going to CLEAN UP!
