Re: Brexit means EDF!
Don't see why the US should be disappointed:
NATO=US+EU. Plus expanded definition of 'North Atlantic' to cover expansion.
EDF=EU+US, if the US is invited to participate.
The Balkans isn't necessarily a good example given it included a US commander demanding we attack Russians who'd occupied an airport. Libya may be a better example, ie French lead with the US dragged in under duress. And has left a liberated Libya, free from the tyranny of Gadaffi.. And now back to running slave markets, Barbary style.
