And the result of all these demands will be that Sharon will say nope (as well he should); the Arab world will continue to be an excuse machine for terrorism; and Yassir Arafat (if he is still around) after the "incursions" will go on being a terrorist who does nothing to stop terrorism.
I'm sorry but hypocrisy and empty demands, with no force to back them up, just make the guy doing them look silly.
Mr. President, honor your principles.
The other result is that it encourages the Palestinians to continue resistance as long as possible, thereby ensuring that the incursion is much longer and bloodier that would otherwise be the case.
