Do you think Britain Owes its very exsistence to America after WW2?

So nationalistic! No, I disagree. Even though the US did play an important role in WW2 and in the post-war Europe, the Germans would never had won as France didn't win with Napoleon and ancient Rome eventually fell apart. Do not underestimate Europe, do not overrate America and do not do things expecting eternal thanks and blessings, if America intervened in one way or another they must have had their own reasons. Regarding the Soviets, Germany obviously didn't stand a chance against them just like Napoleon's troops didn't before them. Btw, I'm not British.
