If that's what they feel needs to be done, then good. I have given up any hope of Europe's capability (or in some cases, desire) to protect their shrinking Jewish minority. Whether the next step is emigration to Israel or a less-hostile Western nation, I can only hope they find the peace and security that various elements are determined to deny them in Europe.
Europe is not a country.
France has the largest Jewish population and the most recent tragedy, but the harassment, intimidation, and terrorizing of Jews is a continent-wide problem right now.
