This month, when 359 Somali and Eritrean migrants drowned in a single boat, nobody even had a satellite phone to summon help. Every sinking brings stories of parents who could swim, but had to choose which children to save.
"For us it's intolerable that the Mediterranean is a sea of the dead," said Prime Minister Enrico Letta of Italy last week, announcing that his country is tripling its air and naval presence in the death zone. But as Interior Minister Angelino Alfano warned, "It's not a given that the intervention of an Italian ship will mean that migrants are taken to an Italian port."
They don't want the migrants to die, but they don't want them to stay in Italy, either. As in other European Union countries that are getting a lot of asylum-seekers, the flood of migrants from Africa and the Middle East is fuelling a powerful anti-immigrant backlash.
The brutal truth is this: the safer the EU countries make the Mediterranean crossing, the more people will try to come.
Most of the migrants currently risking their lives in those little boats are genuine refugees, but behind them, in the vast sweep of countries from West Africa to Somalia and Iraq, are several hundred million others who would leap at the chance of moving to Europe. The nationalists in those countries will indignantly deny that, but you only have to talk to ordinary people there to know that it is true.
Behind all the humanitarian talk there is the stark reality that the EU will never make it so easy and safe to get in, so that even a small fraction of that vast reservoir of would-be migrants actually tries to make the journey. European leaders who let that happen would be committing political suicide.
The least bad solution would be to encourage the emergence of stable governments in Tunisia and Libya that could stop the boats from leaving their shores, but that will not happen any time soon. In the meantime, people will go on drowning in the Mediterranean, although hopefully in smaller numbers than the catastrophe of the last few weeks.
