This was always confusing to understand, but now that it is being brought to light, I have more understanding on the issue. I respect Rabbi Gilad Kariv when he says that their conversions have been respected for the past 20 years. It has to do w/the fact that these 400,000 Russian immigrants did for the most part, not arrive to Israel via America, and therefore are not like American Jews who are for the most part, although I do not know for sure, Reform Jews. But since it affects Conversion as a whole, Reformist Rabbis are duly concerned. Why did Likud give a free hand to Yisrael Beitenu? That is indeed cowardly, though the issue does indeed need to be resolved, since Russian immigrants are the largest group to make Aliyah since the early days of the State, apart from the Ethiopians.
