Iran nuclear talks enter the decisive, dangerous endgame Thursday with a marathon final round of hardball negotiations potentially going all the way to the July 20 finish line.
The deal being sought by Iran and the five permanent members of the UN security council plus Germany would finally ease fears of Tehran getting nuclear weapons — and silence talk of war for good.
With insurgents overrunning large parts of Iraq and Syria in chaos after years of civil war, this could help Tehran and the West normalise relations at an explosive time in the Middle East.
