Shas never apologized for the crime they committed against the Jewish people by enabling the Oslo accords to be imposed upon Israel.
The belief that you can surrender Jewish land to save lives is absurd, and is rejected by the vast majority of Israel's rabbis. If saving lives is the priority, then we can never wage war. Because in a war, lives will be lost. Yet we believe in the Torah concept of milchemet mitzvah (an obligatory war). How can we have milchemet mitzvah if saving lives is the number one priority?
With all due respect, HaRav Ovadia's decisions have indeed caused the deaths of countless innocent Jews. And his party, Shas, is the most corrupt party in Israel.
I am happy to see that HaRav Ovadia doesn't want people in Israel who sell pork. Which doesn't mean that Shas is not responsible for aliyah: Shas was directly responsible for the aliyah to Israel of the Arab Hitler Yasser Arafat and 80,000 Muslim terrorists as part of Oslo.
In the last election, Aryeh Deri, the founder of Shas whom HaRav Ovadia has praised as a "saint", urged people to vote for the radical leftwing Kadima party and served as a special election advisor to Ehud Smolmert. Deri was convicted of bribery, kickbacks and gross corruption, and served four years in prison. But HaRav Ovadia insisted that Deri is innocent.
BTW, I know Shas leaders and I believe that they genuinely dislike Ashkenazi Jews in general and Russian Jews in particuliar. Shas subtly appeals to anti-Ashkenazi and anti-Russian prejudice in their campaigns.
But at least Shas did one good thing: they expelled a Jew named Chaim Ben Pesach from Israel. We wouldn't want this Kahanist troublemaker preaching love of all Jews, including Ashkenazim and Russians, to Mizrachi youth. We wouldn't want this troublemaker telling Mizrachi youth that we are not allowed to surrender sacred Jewish land under any circumstances (most Mizrachi youth are also against giving up land, so this issue could be a problem for Shas). Most of all, we wouldn't want this troublemaker to remind Mizrachi youth that Shas has been proven wrong on every issue, while the Kahanists have been proven right.
Despite all that is written above, we should not disrespect Torah scholars like HaRav Ovadia. But when other Torah scholars disagree with HaRav Ovadia's radical left positions, we have a right to be respectfully critical.
