And if the UK didn't have a sea border, do you think we would have repelled Nazi invasion force ?
Italy was a UK ally in WWI by the way.
Not much good they done then either

That hypothetical situation is silly, Britain's reliance was on the Navy, if we didn't have a sea border I don't think it would have been the most important service!
Sure we would have been buggered if there were no channel but Britain has adapted to being an island and was mainly based on naval dominance, who knows what Britain would be like if we were....joined to the cheese eaters...
