European Offence

Various people have tried, and failed, to create a European super state through military means.  The historical list includes Adolf Hitler. The EU is also trying to create a European super state, but through political manoeuvring.  Boris Johnson points out that the EU, like the military dictators before them, will also fail because there is no fundamental and underlying loyalty to a “European” identity in the EU.  So what is offensive about that?  Surely Boris bashers could not be imagining that Germany was behind the EU drive towards a super state?
