Never again...

You may very well think that the Prime Minister's statement that Brexit could increase the risk of war as being way over the top.  I certainly do, but I think it's worth remembering that the original idea of the European Union was born back in the late 40s and early 50s specifically out of a determination to try and make a third European war "unthinkable and materially impossible".  The question is whether seventy years on that danger is really still there.
