Abu Bakr al-Baghdadi is the leader of the Islamic extremist group ISIS, which has claimed responsibility and inspired deadly terrorist attacks around the globe, including those in Paris and San Bernardino, California. The U.S. State Department in 2011 announced a reward of up to $10 million for information leading to his capture or death.

Vladimir Putin, the president of Russia who allied with Syrian President Bashar Al-Assad against ISIS, sent air force jets on bombing missions to fight the terrorist group’s influence. His actions have helped earn the president a reported 90-percent approval rating in Russia.

Iranian President Hassan Rouhani signed a deal with six global leaders limiting his country's nuclear program in exchange for the lifting of economic sanctions. His work to improve economic relations with the West was bolstered by a November trip to Europe.
