The Arabs could have had the allocated land in 1948 and they really had it in 1967, yet they went out for war. And Israel get's the advice to make peace. The Palestinians interpreted land - as all of Israel. And only one small incy wincy request they where shy to put on the table - the return of millions of Arabs to Israel. Sharon may be able to protect Israel's safety better against the attackers, but he will not be able to achieve peace.
Nobody can make peace alone.
They just strengthen the aggressors in their demands. Israel is ready for peace since ever. The Arabs are not. This is the whole truth. It would be helpful if the pitty given to the Palestinians would shift to the Israelis, who where deprived from a day of peace since their existence.
