Calais migrants: who caused the problem in the first place?

Resurgence of worry over migrants camping at Calais, desperately trying to get their fingertips of a moving UK bound lorry.

We may wonder (a) where they are coming from, and (b) what makes them so desperate to come to our unwelcoming shores?

Answers: (a) Iraq, Afghanistan, and Somalia.
(b) War. Which in the case of the Iraq and Afghanistan was decided upon by Mess(e)rs Blair T and Bush G.

In a perfect world, Blair would be sent to Calais to sort out the mess that he helped to bring about. Bush could help him by arranging to erect his tent and cook the food on a camp fire. He'd be good at that. Maybe.
