The first and most radical vision of a unified Europe was dreamt up by Churchill in one of his speeches just after WWII (before he became the prophet of the Cold War). I think if pro-European Brits would dig it up and use it often (this is one of the many things Bliar with all his rhetorical talent failed to do), it could have been made relevant again.
