Over on Twitter, The Atlantic’s Jeff Goldberg and COMMENTARY contributor Jamie Kirchick have been debating whether the threat to the Jews from neo-Nazis is worse than that of Muslim Jihadists. This argument was brought up by the allegation, which may now turn out to have been a false lead, that the Toulouse massacre was perpetrated by neo-Nazis rather than Islamists. Goldberg’s point is a good one. The Nazis stand alone in history and ought not to be compared to any other genus of Jew-hater or tyrant. Goldberg is also right that Nazi analogies are almost always wrong since there really is nothing in history that compares to the Holocaust. As bad as Iran or Hamas or Hezbollah might be, and they are deadly threats, they are not the same thing as Adolf Hitler and Nazi Germany.

However, if we are discussing what Jews and other civilized persons should be worrying most about today, the idea that there is any comparison between the danger posed by the scattered bands of neo- Nazi extremists and that of Islamism is not a serious proposition. The neo-Nazis are a nasty bunch and capable of violence. But Islamist terror has at its command, terrorist armies, control of sovereign territories (Gaza, Lebanon and a major state such as Iran) as well as the resources to finance a nuclear weapons project. While the persistence of Nazism, even in its current truncated form is upsetting and makes us wonder whether Western civilization really is in trouble, Islamism is a real threat, not a symbolic one.

While we may dismiss this argument as the sort of thing that is, as Goldberg joked, for people with nothing better to do, the fact is, a lot of liberal Jews really are more scared of the dangers that existed in the past than they are of their people’s current foes.

For many liberal Jews (a group that I should stipulate does not include Goldberg), raising the question of Islamist hate for Jews — something that is the source of the rising tide of anti-Semitic agitation around the globe — is somehow in bad taste if not evidence of the dread charge of Islamophobia. They are so conditioned to believe that Muslim distaste for Israel’s actions is the reason for enmity that they ignore the vicious stream of Jew-hatred coming out of the Middle East and prefer to worry about an altogether mythical post 9/11 backlash against Muslims.

Instead, they prefer to dwell on the far less potent danger posed by the tiny groups of Hitler-lovers who are generally too weak and isolated to do anything more than disturb the peace. While such groups are despicable and deserve the attention of law enforcement, to focus on them is to re-fight the last war.

We don’t know yet who committed the Toulouse massacre but we do know that it was the work of a Jew-hater who sought out and murdered Jewish children in cold blood solely because they were Jewish. It would have been reassuring in some ways to think that this crime was only the work of outliers like the neo-Nazis. The thought that it is part of a rising trend of Islamist hate — which has been aided and abetted by the anti-Zionist attitudes of European elites — is far more troubling.

Worrying about Nazis is an exercise that is far less distressing than forcing ourselves to deal with the real dilemmas of our age. Chasing ghosts may be of little utility for contemporary Jewish security, but it is easier to think about than coping with real live Muslim terror.
