"Shooting at them would be so much easier and glorious."
Seemed to work out pretty well last time.
I guess its just lucky for The Netherlands that in 1944 rather than "making jokes and asking even more questions. For a decade and then see how things look" the British, Americans, Australians and Canadians decided to resist the German's aggression and give your ancestors their country back.
You don't seem to either be willing or able to accept that the people who live in the Falklands don't want to be bossed about by the Argentineans. I imagine that in 1940 your grandparents weren't exactly enamoured at the idea of being bossed about by the Germans. Think about it.
