That is a reply.
Peace in western Europe really is quite young, only 65-70 years and the conditions outlined in that guys response are the kind that are likely to create displacement and economic difficulties across mainland Europe.
For all its faults, the EU has created a platform whereby Europe as a whole can coexist without the need for large-scale internal wars. This is a price the UK should have been prepared to bear.
And I know the UK has this (deplorable) arrogance about being an island and somewhat immune to the effects - but it's something we need to seriously guard against. Especially with upcoming elections in the US (and deep internal social issues), France and Germany. Spain being content to have no Govt (be interesting to see how that pans out), Russia bombing Syria and whatever fallout comes from the west regarding Assad's position.
Without wanting to sound melodramatic, I think we are heading for some real worldwide instability if a couple of scenarios go a fractious way
