More here on the Hamas reaction.  (HT: DrudgeReport).

I am being told by callers and e-mailers that this is the sort of heinous attack on a sacred place that can change Israeli politics in the blink of an eye.  Dennis Prager will join me at the top of the next hour to discuss.

From Yoni:

If Olmert does not get his act together and respond like a real Prime Minister to the daily rocket attacks and today's murderes at Mercaz Harav Yeshiva, bad things will happen.

If you don't understand the ramifications of this targeted attack, let me give you some background Mercaz Harav Yeshiva is considered the leading national-religious yeshiva in Israel, with hundreds of elite students. Among its thousands of graduates are leading public figures including senior rabbis and IDF officers. It was founded in 1924 by mandatory Palestine's first chief rabbi, Rabbi Avraham Yitzhak Hacohen Kook. Its longtime head, Rabbi Avraham Shapira, died in September 2007.

This is a stab at the heart of religious Zionism, and if Olmert does not strike back, I am afraid that individual Jews will say enough is enough and strike back at our enemies the Arab in acts of retaliation.
