British policy since 1700 has been to prevent any one power or coalition from dominating Europe. To this end they have allied with the Germans against the French, the French against the Germans, the Russians against the Germans, the French against the Russians etc. etc.
The British by being in the EU have counter-balanced the French a lot and made the EU more business friendly. Churchill would have stuck in the EU and formed an alliance with the remaining 60% of EU GDP to balance the French and Germans. Also, since Hollande has come on board, Angela has in fact been closer to the UK position.
Yes, this. Said.more eloquently than I could. Brexit is incredibly stupid.
Oh look, a Pole. Now why do they love the EU so much? Hmm...
