John Oliver address this point, though in a very different way. And given that this is John Oliver -- wonderfully. And at times hilariously.
(I'm surprised that the one thing he left out was how Britain reacted as a nation during the time it actually was under siege, during the Battle of Britain with Hitler's bombing during WWII. And even then, from all accounts, England went on pretty admirably.)
My only complaint is that it's only 2-1/2 minutes.
