UK stands alone in Europe-again

It's hard not to draw parallels with 1940. Then the UK stood alone against the evils of Naziism our only allies coming from the Commonwealth and the United States. That's how it seems today; the mainland European countries are uniting in following the German agenda to marginalise the UK for daring to leave the great experiment; to finish what was started in the nineteen thirties. Why would they do that? Could it be that without the German economy, most of the 27 Countries of Europe would be vastly worse off and therefore they fall into line.
I wonder if, in five years time, these Countries might look to the UK, once again, to rescue them from their own folly?
