I agree with Netanyahu. In recent years, the US has been a horrible partner at the negotiating table. If the US is discussing a solution it is almost guaranteed that the only consequences for the country in trouble is 'severe talking to.' Israel should be concerned, so should any enemy of Iran. Nuclear technology is not something that every country should feel free to incorporate into their military. It is a direct threat to the US and our allies for other countries to have nuclear weaponry and thus we have an interest in how that technology is developed and used.
