Interesting that you glaringly left something out here. In your first sentence you state the facts, but from then on you lay all the blame on Israel. If both sides refuse to budge, would it not be fair to say that the Palestinians and Abbas/Hamas show no interest towards peace either and have done nothing towards moving closer?
Everyone keeps claiming that the Palestinians keep setting pre-conditions, but ignore the fact that Israel does the same (which you never seem to mention).
None of these preconditions are conducive to negotiating peace.
Second - everyone, including you,
keep blaming the Palestinians for lack of progress but it isn't just the Palestinians, it's Israel's actions or lack there of, that are contributing to this as well. You never seem to bring that up either.
Since Netyanahu has been in power - what specific steps has he taken to move the process forward? He seems quite happy to keep the status quo. Sharon did more than Bibi in regards to this which leads me to think Bibi does not truly desire peace and feels if he stalls long enough Israel will get everything and the Palestinians left with a permanent occupation/semi-automous status which will not reduce violence.
