Two Graphs Show the Nuclear State of the World

Early Tuesday morning, while most Americans were still sleeping, the U.S. completed negotiations on a historic nuclear deal with Iran.

President Obama stated that the deal will block "every pathway to a nuclear weapon" for Iran. In exchange, the U.S. and other E.U. countries agreed to lift international oil and economic sanctions.

Nuclear disarmament has long been one of President Obama's top foreign policy priorities. In fact, in his first major speech on foreign policy in 2009, President Obama described his vision of a "world without nuclear weapons." How will the Iranian accord affect this long-term goal of global nuclear disarmament?

Using data from the Federation of American Scientists and the WISE Uranium Project, InsideGov mapped the nuclear arsenal of each country around the world. As the graphic below shows, Russia leads the world in nuclear weapons with 7,500 warheads. The U.S. is a close second with 7,200. France is a distant third with just 300 nuclear warheads. Overall, there are nine countries with nuclear weapons.

President Obama will need to convince allies and rivals alike to reduce their nuclear programs. But his biggest challenge might be convincing the U.S.
