I don't judge any world leader by his agreements or disagreements with other world leaders. I'm sure you don't either. I judge them on whether I think they are right or wrong. Faulting Sharon for responding to terrorist acts seems a little silly when you yourself have responded in similar ways to terrorist attacks.
Either Bush is wrong to respond with military force in reaction to terrorism, or Sharon is right to respond with military force in reaction to terrorism.
Very telling that you say you don't judge any "world" leader, but I'm talking about the president of the U.S. You judge American policy on whether or not it coincides with Likud policy.
