In the time-honored tradition of the college activist, 23-year-old Yosef Rabin organized a mass, coast-to-coast US rally to be held Thursday, on the Fast of Esther at 12:30 p.m. EST, to express American Jewry's solidarity with Israel.

The 23-year-old Chicago native -- aided and abetted by the Amcha and Jewish Activist Network organizations -- organized rallies to be held at Israeli Consulates in New York, Boston, Atlanta, Miami, Houston, Chicago, Los Angeles, San Francisco and Washington DC. The Women in Green organization also made sure the announcement was sent out to its members as well.

The Fast of Esther ends at sunset with the beginning of the holiday of Purim, which commemorates the last-minute salvation from a plan by the Persian Prime Minister to annihilate the entire Jewish population approximately 2,500 years ago.

Rabin saw the attack by an Israeli Arab resident of a Jerusalem suburb who slaughtered eight young students and wounded 11 others at the famed Mercaz HaRav Kook Yeshiva two weeks ago as an echo of the past.

In an exclusive interview with Arutz-7, Rabin said the scheduling of the rally was no accident.  "Everything the Jewish People does must have spiritual and physical components. The Jews in Persia fasted, and then went to war," he pointed out. "This attack and every attack is not only an attack on Jews, but an attack on HaKadosh Baruch Hu – our honor and His honor is one."

The young activist took the attack personally, having also learned in Israeli yeshivas, at Yeshivat Torat Chaim and Yeshivat Torah Shraga, then following up with a stint in the IDF's Nachal Hareidi through Machal, before returning to the US complete his degree in political science.

Rabin, who said he will make Aliyah (immigrate to Israel) when he completes his studies, maintained the yeshiva attack was not just about killing Jews.

"The fact that they struck at a yeshiva, the very symbol of holiness, just pushed me over the edge.  Now more than ever we need major action," he said.

"The Arabs showed that this is not just a war over land; this is a war over our very souls as well. There is no difference between blowing up a bus with 'secular' Jews or shooting yeshiva students learning Gemara (Talmud). This is a clear war against the A-mighty G-d of Israel!"

Rabin told people on the Facebook site to "go out and cry out OUR BLOOD IS NOT CHEAP."  He noted with some irony that the Arabs are ahead of the Jews when it comes to asserting themselves. "You know, there is one thing that I am willing to learn from the Arabs, and that is their sense of self-respect," he said. "One guy makes an anti-Mohammed cartoon and the entire Arab world stands up and says, 'that ain't gonna happen again.' Why can't the Jews have the same respect for themselves?"
