Well in for a penny... we might as well all vent our collective spleen on this quiz now that I've also given an answer away.
You wouldn't call a destroyer a "major warship", so why on earth would you put a U-Boat in that category? It's not even a ship.
I got the 20-year mutual assistance treaty question wrong, like Oberon, which is fair enough. And I didn't use any of the 'hint' buttons, whatever they did.
