The Palestinians will not return to negotiations, listen the USA or the Quartet. That chapter of history is closed. They are impervious to their threats. When you have got nothing, you have got nothing to lose. European , UK , and Australian public opinion has turned strongly against Israel and in favour of the Palestinians. In time their politicians will follow their populaces. The USA will be the last domino to fall, as their population is the most naive, isolationist, and religious. The Palestinians will eventually gain political and economic rights, in what type of state system is yet to be determined. Israel has grossly over played its hand, and is living in a fools paradise regarding the strength of its support outside its country. Oh yes the only ones concerned about Iran are the USA (due to pride/paranoia), Saudi Arabia, some gulf states and Israel.
