You are dealing with "what if" and I am dealing with "what is."

But it's still a moot point.

Unless Britain decides to impose Eastern bloc cold-war style emigration prohibitions, there is no way that they can reasonably expect to stop their subjects from leaving the country to join foreign armies.
