There is NO doubt. Not to disrespect any other names that have been, or will be, mentioned here, BUT…
THE Greatest Jew of the decade is definitely Roi Klein ztzvk”l.
This young man, as hopefully most of you remember, sacrificed his life al Kidush HaSh-m, ha’Am, v’ha’Aretz by throwing himself on a hezbollah hand grenade in the 2nd Lebanese War, to save the lives of his fellow soldiers.
Those who have seen the video or read the book about his life, know that this incredible act of heroism and self-sacrifice was NOT an isolated incident but the culmination of a life lived EVERY day for HaSh-m, His Torah, His people, and His Land.
ROI KLEIN, an exceptional Tzadik.
Yehi Zichro Baruch.
