Quite apart from other problems caused by #Brexit, there is a likelihood that in #geopolitical terms, the move to leave the EU may have been a major mistake in strategic terms.

If the world (as Simon Tisdall, plausibly suggests) is starting to coalesce into competing (large scale, continental) blocs, then being a disconnected island off the shore of Europe may be less 'freedom from' & more 'vulnerability to' other states' strategic decisions - post imperial hubris?
