First, the whole issue is very emotionally laden. The problem is, that for some time Israel has declared that there is no partner and therefore no one to discuss border issues with, or nay issues for that matter. These decisions, as you admit, cannot be made unilaterally and I do not think Lieberman has any intention of consulting the Palestinians over his ideas on transfer. I have always advocated mutually agreed upon border adjustments but they must start from the premise that all of the WB and East Jerusalem must be under Palestinian sovereignty. Any changes would have to be reached through negotiations and be equal kilometre for kilometre. Personally, though I have and still do support a two state solution, Israel is clearly moving against that option.
