Israel has no more or less right to exist tan any her stet. Israel came into existence through military aggression and usurping other people's land.
As somebody said, if you legitimize the actions of the Jews, you can not delegitimatize the actions of Palestinians.
The initial causation of the troubles today was Jews unilaterally declaring a state taking Arab land in the process.
They declared the state unilaterally because it was obvious that talking wasn't going to work. And I don't have a problem with the majority of the occupants of a land making a state on that land.

It is a fact the Palestinians resumed seeking diplomatic actions after the Israelis balked at fulfilling their part of the initial agreements, namely the release of 104 prisoners. These deals are not one-sided. If the Israelis refuse to carry out their commitments, the Palestinians are under no obligation to carry out theirs.
What you're missing is that they didn't release the prisoners because the Palestinians weren't upholding their side of things. We see the same thing over and over--history is always started with the Israeli actions, not the Palestinian ones.
