U.S. President, Barack Obama praised Thursday the preliminary deal agreed on by the U.S., Iran and five world powers to contain Iran's nuclear program. Obama said it was a "good deal," describing the agreement as "a historic understanding with Iran which, if implemented, will prevent it from obtaining a nuclear weapon." I am convinced that if this framework leads to a final deal, it will make our country and the world safer," Obama added. He affirmed that military conflict will be taken in consideration in case Iran did not commit to the agreement terms.
