The thing is, we Brexiteers don’t care about the UK’s role in world affairs. To want to control other people or be controlled by them is a very leftie desire. Brexiteers merely want as few layers of “management” above or below them as possible. And what layers there are should be democratically chosen.
Well, I guess a no-deal Brexit, a devolved Scotland, a reunited Ireland, (I don’t think people care much about Wales), and Singapore status for London should leave England proper needing relatively few layers of management. And they can all be Tories (of the right kind, not the moaning ones). Great again!
