the world sits by and watches as iran, an openly hostile nation, is on the path to building weapons of mass destruction. Israel MUST deter them BY ANY MEANS NECESSARY and probably will. The world wants Israel to do their dirty work but by doing so they may hurt themselves. If a full scale conflict develops between Israel and Iran Israel will smash their nuclear capability before it begins, Iran may retaliate and Israel may have no choice but to finish them off. In this scenario Iran would be a post nuclear wasteland making it impossible to get to the oil and seriously limited the world's supply.
