Re: No . . .
The Sharon line is that Arafat turns a blind eye to Hamas, and getting rid of Arafat so the Palestinian government (whatever that is) may be revitalized for peace is anything but irrelevant.
My guess is that there is only one thing that may, and let me emphasize "may", keep the Israelis and Palestinians from going at each other, and that is a UN deployment.
You still haven’t mentioned what nation you think might be willing to step into the blue helmet shooting gallery. As it stands, only the United States of America has the overall power to do anything in the region, and I don’t see us clamoring to get troops implaced.
