Europe has been in the grips of the worst refugee crisis since the Second World War, but it could be about to get a lot worse. That is the perspective from Lebanon, which has taken the brunt of Syria’s exodus and is now at breaking point. Coming to the small Mediterranean nation also helps explain why the crisis has suddenly erupted now.
Lebanon is a truly remarkable country. For the last four years, it has absorbed at least a quarter of its population in refugees. While Europeans agonise over a refugee crisis, but a real one has been under way here. Imagine the UK being invaded by the population of London twice over. Refugees are everywhere, camped in fields, lay-bys, beaches and building sites.
Then imagine that in a Britain that hasn’t had a functional government for months, where garbage collects in festering piles because authorities can’t even agree on the most pressing challenge: clearing the nation’s rubbish.
