Would our ancestors be turning in their graves if they realised their sacrifice in two World Wars were in vein?

For centuries it has been in Britain’s national interests to hold the balance of power in Europe, they fought two World Wars to hold on to that status when fractious European nations and their expansionist ideology threatened Britain’s security.  Apart from the economic consequences, what the political repercussions of a Brexit from the European Union are, in the long term remain unknown but arguably, anti-western leadership must be rubbing their hands together anticipating the time British power on the continent is quashed once and for all.  Obviously, it is too soon to assess the outcome, but if history is any indication, then the after-effects of Britain’s exit from Europe are not reassuring.
