Pitching your tent for weeks on end in the cold and mud, with no power or plumbing. Running in a pack after accelerating lorries and clutching frantically at the back door handles. Risking not only your own life but even the lives of your children by crowding into unseaworthy dinghies, in which to drift precariously across the busiest shipping lane in the world… All this full-tilt determination to flee intolerable circumstances and get into the comparative Valhalla of the UK makes perfect sense — if the place you’re so desperate to leave behind is war-torn Syria or famine-ravaged Yemen.
