An interesting post on EU Referendum today regarding the need for clear reasons to be expressed about the UK's future on getting out of the EU, not just the anti-EU stuff but A Postive Object. The post refers back to WW2 and how war isn't just about the fighting: modern' political issues in 1940, far from being just "War!", were being widely discussed, one such being European political integration: "all in the more general context of defining British "war aims". It was not simply enough to fight and win, we had to have a reason for fighting, or so the argument went."
Churchill wanted status quo and suppressed any debate on the issue; Richard Stokes, Labour MP for Ipswich, said to Churchill's Information Minister Duff Cooper (who apparently agreed there was a need for a statement on war aims) "[It] is no use fighting for a negative object. You must have a positive one, and the sooner that [is] stated the better". And hence to the present and the EU.
"It is all very well wanting to get out of the EU – the "negative object". But what would we do with our new-found freedom? Where is our "positive object"? Until we have one, we are going nowhere. We emerged from the war without one, and that is why we lost the peace."
