After the attacks in Paris on Charlie Hebdo and a kosher supermarket in early January, France's Prime Minister Manuel Valls said "France would no longer be France without its Jews". Following last weekend’s desecration of a Jewish cemetery in Alsace, President François Hollande has said the republic would protect French Jews with "all its strength". But a growing minority of France’s estimated half million Jews, the largest community in Europe, see their future elsewhere, and notably in Israel.
