It rather baffles me what the problem is the French have (other than no interest). When lots of migrants were crossing from Turkey to the Greek Islands last year, the EU gave Turkey a sum of money and the Turks stopped it. The Turks regularly patrol the areas concerned. OK, the very occasional dingy gets across, say no more than 1 per month. If the Turks can do it, why can’t the French? Yes, I know the answer, and that is the problem.
