It seems almost counter-intuitive that Netanyahu, who is a smart politician, talks tough just at the time when it seems that the rest of the world and Iran might actually talk.
Not being much of a politician myself, I thought this. On a political front, Israel is pretty well isolated and has nothing to lose, no friends to alienate by acting tough. What everyone else, every other government that is, would like to see is Israel shut the hell up and let the Iran thing quiet down.
But then there is always that real chance that, without Israel threatening attack, talk would happen and, under lesser pressures, those at the table who don't want confrontation would back off from their stance about Iran having nuclear capacity, hoping that it would never come to that.
So, Bibi is holding everyone's feet to the fire. 'Get in there and make this happen or we will do something.'
Whether he means it or not, I have no idea but Iran as a nuclear power in the middle East is a terribly unstabling situation.
No sensible person is concerned that Israel would actually use a nuclear device but the thought of Iran, a state that sponsors terrorism, with the capacity to deliver/lose/misplace a nuclear device into the hands of actual terrorists is something that should make everyone lose sleep.
