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.
Realistically, America is just as Anti-Semitic as most of Europe. We just don't report as much because there are so many racial/ethnic groups to offend.
