According to the agreement between "Iran" and "China, France, Germany, the Russian Federation, the UK and the US", Iran should not be able to produce weapons of mass destruction.
But in reality the progress of Iran's nuclear program is still unknown!
(And also situation of war in the Middle East is quite uncertain. All countries are at war with each other.)
What are the conditions of Iran's nuclear agreement?
Is it really practical agreement (or just an agreement on paper)?
