But perhaps more seriously I am expecting food and medicine shortages; and massive economic disruption leading to a big upswing in poverty - people will die because they have to choose between paying for heat, or paying for food. It already happens every winter, much more commonly now than before the insane 'austerity' policy that shows no sign of abating; But Brexit will make it far worse.
Oh wow. So it is your prediction that because Britain pulled out of the EU, there will be a complete and utter trade embargo between the two, that the UK will become a third world country, that all the trade they currently do all over the world will vanish over night, etc.
Will there be waves of refugees crossing the channel to get into France? Will France have a second and very different immigration problem?
You'd have been on more realistic grounds had you predicted the EU ordering limited military strikes with no boots on the ground.
