Until the USA steps back from their blindfolded support for Israel, nothing will ever happen. The good news is that this just a matter of time.
What I find absolutely hilarious by the way is when people claim that the palestinians shouldn't go to the UN to ask for statehood recognition, because the only acceptable way for the palestinians to get their own state is through direct negotiations with Israel. Whoever says something like that is either a complete idiot parroting some crap he's heard on TV or simply trying to fool complete idiots.
Israel has no intention whatsoever to give the palestinians their own state. Why should they?!? Apart from gaining popularity, there's just no advantage for them.
Israel's ruling party even explicitly states in their party program the aim of preventing the establishment of a palestinian state.
So telling the palestinians that direct negotiations with Israel is the only acceptable option is as ridiculous as telling the jews in warshaw ghetto that direct negotiations with the Nazis is the only acceptable option to improve their situation.
Btw, I wonder if the current tensions between the palestinians and Israel might indeed have to do with the palestinians going to the UN. It seems that Netanyahu and Co. are seriously afraid of them doing so.
