Last I heard Ariel Sharon was in a coma, so he's probably out of it. However, there's a chorus of his coherts, the neocons who designed the Iraq war which is such a disaster, that have been urging us to attack Iran. You could say that the Israeli assault on Lebanon was a skirmish, in these neocon's minds. Last I heard, we had a few battleships near Iran. If we attack Iran, that will be the start of World War 3. I think this won't happen, as there are enough US generals who realize it would be a disaster times 10.
At the time he went into his coma, Sharon had his hand in the murder of more innocent people than all the Islamic terrorists combined. Perhaps that's one of the reasons his visit to the dome mosque caused such an uproar. Besides, after Israel destroyed hundreds of mosques inside Israel, and coming on top of years of foreign occupation by a country intent on taking as much land as it could get with as many Palestinians forced out as it could get away with, poverty induced by military restrictions, land confiscations, suppression of political protest and apartheid, laying claim on behalf of Israel to another Islamic holy site was a last straw.
