As mentioned at the Michtavim blog, forty-year-old Rav Yitzchak Dadon, shlita, was the first to shoot at the terrorist following the massacre last week at Yeshivat Mercaz Ha-Rav in Jerusalem. Rav Dadon studied for many years at Yeshivat Mercaz Ha-Rav and is the author of over a half-dozen seforim, including the very-celebrated and landmark two-volume set, Atchalta Hee (2005 and 2007), on the relationship between Zionism of religious leaders from the Ashkenaz and Sefaradic communities to Zionism and the establishment of the State of Israel, as well as an excellently detailed-survey (in both volumes) of poskim of earlier generations who have dealt with the related issue of Geulah be-Derekh ha-Teva in their own writings.
See below for the very-admiring mikhtav berakha from former chief rabbi of the State of Israel and Rosh Yeshiva of Yeshivat Mercaz Ha-Rav, the late Rav Avraham Shapira zt"l, to Rav Dadon's Atchalta Hee, available below. (Copies of Atchalta Hee are available from Biegeleisen in Boro Park 718-436-1165.)

As I wrote at the Michtavim blog:
What a Kiddush Hashem it is, and praiseworthy is Rav Yitzchak Dadon and all other talmidei hakhamim in the yeshivot Hesder who are not only tremendous Torah scholars like David HaMelech, but are also similarly able to protect Am Yisrael and destroy our enemies when necessary.
