As tensions rise over Iran’s nuclear program, diplomats from six countries will meet with Iranian officials in Turkey on Saturday. The talks will be taking place against a backdrop of strict sanctions against Tehran for what the West sees as its ambitions to build nuclear weapons. Though Iran will have more than one chance to reach an agreement, analysts believe this weekend will be their best shot. The sanctions against Iran are expected to get worse, which will make it harder for the country to negotiate. President Obama has publicly stated that Iran cannot obtain a nuclear bomb and has not ruled out military intervention.
