Recently, a number of U. S. senators signed a letter directed at the leader of Iran to tell him that if he made an agreement with the current president, it could be undone by the next president and by Congress. The senators disagreed with the president’s goal of striking a deal with Iran over nuclear weapons. The letter said that the Congress could modify the agreement at any time. Were the senators correct in their assertions? No, because the Senate and House of Representatives have no role in United States foreign policy.

No, because the agreement would be signed by the Iran and U. N. Security Council member nations.

Yes, because any agreement made by the president is subject to congressional approval.

Yes, because the president does not have the right to make agreements with other countries.
