The least surprising thing about yesterday's turn of events in Paris is that Jews are the target. Because when it comes to home-grown anti-Semitism, France leads the world.
A survey last year from the European Jewish Congress and Tel Aviv University found that France had more violent anti-Semitic incidents in 2013 than any other country in the world. Jews were the target of 40 per cent of all racist crimes in France in 2013 - even though they comprise less than 1 per cent of the population. Attacks on Jews have risen sevenfold since the Nineties.
No wonder Jewish emigration from France is accelerating. From being the largest Jewish community in the EU at the start of this decade, with a population of around 500,000, it is expected by Jewish community leaders to have fallen to 400,000 within a few years. That figure is thought by some to be too optimistic. Anecdotally, every French Jew I know has either already left or is working out how to leave.
Natan Sharansky, the former Soviet refusenik who is now chairman of the Jewish Agency, said last year that 2,254 French Jews moved to Israel during the first five months of 2014, against only 580 in all of 2013. That is a staggering 289 per cent increase, but in recent months the figure is thought to have increased exponentially.
The number expected to leave this year for Israel was estimated at more than 10,000 - and that was before today's events. And that is just to Israel. Many are coming to Britain as part of the wider French exodus under President Hollande.
