That right is about as fuzzy as they come, and not one of the permanent members of the security counsel want to enforce that one.
Here is a short list of reasons why:
China=Tibet
Russia=Tchecnya (have NO idea how to spell that in English)
US=native americans
UK=Northern Ireland
France=French Guyana, Bikini atoll etc
I don't know about the others, but the US has nothing to fear from native American self determination, and Northern Ireland already has self determination. A large majority wish to remain part of the UK.
Water rights
Status of Jerusalem
Right of Palestinian refugees to return
Right of Jewish settlers to live where they live now.>>
I think Barak had offered the PA what they claimed to want on all of these except #3.
Barak offered the Palestinians limited control over some Arab areas of East Jerusalem, but no sovereignty over the area.
He agreed to the right of return of around 100,000 refugees.
Water rights were to remain with Israel, and the Palestinians get an increased "quota"
Almost all the Jewish settlers would remain in place, with some very odd borders drawn up to encompass them.
Sharon has ruled out negotiations with the Palestinians until some undefined date in the future, and has made great efforts to stiffle any political contacts that did take place.
The new Labor party (2nd largest party in Israel) leader, Mitzna, is promising immediate negotiations, and a 1 year deadline for them to succeed, before a unilateral Israeli pull-out from most of the West Bank and Gaza.
The only hope for peace is that things can't continue as they are idefinately. Sharon has promised security, but presided over the largest number of attacks in Israel's history. The Israeli economy is in great difficulty, and the cost of keeping the settlements means cuts in the health, education, social security and defence budgets.
