Netanyahu is doing the right thing in trying to convince everybody around the world that Iranian nukes are a threat to world peace. And I doubt that other than Israel's enemies anybody has an argument against it. The problem with Netanyahu is that he also drops plenty of hints that Israel will attack Iran if their nuclear activity does not cease. The plain fact is that Israel cannot stop Iran by itself and its military means. It may be able to destroy a facility, but this will be quickly replaced, and Iranian efforts will only redouble. In the meantime, Israel will buy itself a dangerous enemy who will come up with some retaliation. The "cure" will be worse than the disease. Better promote sanctions and NATO action. The problem with Likud people is that they are unable to see the consequences of their actions. And talking a crazy talk might get Netanyahu to act crazily.
