During the speech at the Cairo University, Barack Obama stated about necessity to expand the U.S.'s relations with Iran.
Last week, the presidents of Iran and the United States stated that possible negotiations between the two countries can begin after the presidential elections in Iran, scheduled for June 12.
"I support those who do not agree that one state should have a [nuclear] weapon, but another not. None of countries should have a nuclear weapon," Obama said.
The Iranian government states that it does not develop a nuclear weapon and has the right to "peace atom". However, production of the highly-enriched uranium by Tehran is potentially component part of the military nuclear program and causes fear of the international community.
