On point analysis of the European migrant tragedies from Chris Bertram:
All European states are signatories to the Refugee Convention and that places obligations on them to offer sanctuary to people who arrive on their shores and who have a “well-founded fear” of persecution (on various grounds). Although politicians like to claim that their countries have a proud history of taking in the persecuted — as Cameron claimed in a speech last year — they now do everything in their power to make it as hard as possible for those seeking asylum to arrive on their territory. Devices such as heavy financial penalties on airlines and other carriers and ever tighter visa restrictions mean that people fleeing countries such as Syria and Eritrea simply cannot arrive in Europe by safe routes, and if they do so by using false documents they are often prosecuted and imprisoned. People from these countries make up a significant proportion of those trying to cross from Libya to Italy. Because people cannot travel via safe routes, they travel via dangerous ones, just as they do in other parts of the world. They put themselves in the hands of people smugglers and they take the risk of crossing the Mediterranean in flimsy boats. But the people smugglers, though no doubt unscrupulous criminals on the whole, are simply responding to a demand that European politicians and their electorates have created.
