Shalom,
This interview may have been posted before but it supports a position I took last Shabbat with my Rabbi in a discussion on Rabbi Kahane (May his memory be a blessing)...
My rabbi is a Chabad Rabbi and the Chabad Rebbe (Rabbi Schneerson) also takes credit for helping Soviet Jewry during the terrible oppression. I am relieved that my rabbi recognizes, and praises to the point of elevating to the same level as his Rebbe. I brought up the great things that JDL, Chaim Ben Pesach, and the Rabbi Kahane did and everyone agreed that it was a great thing.
Here a Jewish soviet dissident discusses how he believes Rabbi Kahane helped the plight of soviet Jews.
