The funny thing is, I agree with you about the contradictions in recognizing borders for the state of Israel, depending on what they're arguing at any particular time.

The borders of a potential Palestinian state and the state of Israel and the Kingdom of Jordan is one of the most difficult conundrums to consider. I can think of a few "resolutions", none of them really "solutions". I make a huge effort to understand the Israeli side, the greater Arab side, the general Muslim side, and the side of the Palestinians who actually live there. Very few people - from any of those categories - make any effort to understand anybody else's side.
