Nuclear talks will resume tomorrow between Iran, the US and five other countries, and the rhetoric is heating up on all sides of the issue. While the US says an agreement is "close," France says Iran's path to a bomb would still be too easy. Israeli Prime Minister Benjamin Netanyahu says the deal is a threat to its very existence, and Arab nations — including Saudi Arabia — are taking Israel's side. In Congress, Republicans, and some Democrats, say it's time to increase economic sanctions, not to relax them, as the proposed agreement would do. Why are the US and traditional partners so divided? Is a deal or the lack of a deal most likely to lead to war?
