The reopening of the case is interesting because it defines the Jews the way the Nuremberg Laws did and the world does: as an ethnic people, not just a religion. (This is certainly the case for my family of atheists who are ethnically 75% Jewish and 25% other ethnicities who were historically Christian.) The case is also interesting because it recognizes that anti-Zionism is the new socially acceptable way to be an anti-Semite.
Zionism is, simply, the right of Jewish people to exist. To have a homeland, a place to go to. During the Holocaust, many Jews had nowhere to go, as the countries of the world turned them away as they tried to escape before they were murdered. The U.S. blocked many. Every place did. The Jews in the British mandate protested against British leaders who sought to keep them out of their historic homeland, won recognition through the United Nations, and then fought off invading Arab countries.
One can believe in a Jewish state (the definition of being a Zionist) and still favor a two-state solution in which the Palestinians get a homeland as well. That is the view of many Israelis, including my relatives who live there. They dislike Netanyahu and are opposed to the expansion of settlements. They want to see land for peace trades. They also are proud of their nation and want it to continue to exist!
The reason we have relatives who live there is that our relatives fled Europe for their lives during either the pogroms in the late 1800s or the Holocaust later. In one family with four siblings, one made it to the U.S., one made it to Israel, and the other two were killed during the Holocaust.
We do not consider ourselves part of the nationalities that tried to kill us. We never were accepted as those nationalities but always treated as “other.” So whenever there is a multicultural event to celebrate one’s international heritage, and you need a flag to represent your country of national origin, I use the Israeli flag. None of my direct ancestors within living memory lived in Israel. But is the only country Jews ever had, both in ancient times and in present times.
Anti-Zionism is the new way of expressing anti-Semitism, basically saying Jews are only welcome to exist as a minority within other nations, subject to periodic tides of anti-Semitism in those countries. It singles out Israel, the mideast’s only democracy (albeit one subject to the strains of a less-than-democratic and xenophobic movement right now, as is the United States!), for special censure. Why do that? Simple. Anti-Semitism. And this interpretation is supported by the fact that anti-Zionist movements on college campuses have often led to comments against Jewish students, instances of swastikas and anti-Semitic cartoons, etc.
You can be opposed to Netanyahu and current policies in Israel and not be an anti-Semite. You can favor a Palestinian state alongside Israel and not be an anti-Semite. But to be opposed to a Jewish homeland altogether is anti-Semitic.
