Negotiation between Israeli and Palestinian has been failed .What is the alternative?

The alternative for palestinian is to go to UN

It was not important 100 years ago and it will cease to be important a 100 years from now. Nature will take its own course. Israeli power comes from western support due to their complicity in WW2 when Jews were being killed. The Arab leaders don't seem to show a long term vision or strategy, looking for in the moment short term wins. The really interesting situational change will be if the West declines and Arabs gain power. Till then, it will very much be the status quo, there is no alternative. All interests are too deeply entrenched. Only a breakdown of some form will lead to change.

"Palestinians are under the longest occupation in the history of mankind"

Even if one is to concede that the so called occupied territories are occupied, that is such an over exaggeration it is ridiculous. Israel only took those areas in 1967. Ancient Rome occupied countries for hundreds of years. Even in modern times there are examples. China has occupied Tibet since 1950.

The Palestinians have continuously rejected any offer of statehood, included an offer in 2000 of 91% of the west bank, extra land in Israel plus East Jerusalem as a capital. The Palestinians need to start questioning their own leaders and ask them why they would rather fight Israel than except offers of a state. That is what we need, a Palestinian leadership who are willing to except Israel, to remove calls to destroy Israel in their charters and then learn to live in peace.

Take both leaders to world court at the Hague and settle it there once and for all arbitrary.Decision shall be final.
