The two countries had to commit to maintaining close and effective surveillance of their common border and to ending any intervention on the territory of the other. Iran therefore had to end all support for the Kurds. The two countries agreed to be good neighbors. A violation of part of the agreement “goes against the spirit of the Algiers agreement.” The border dispute settlement agreement later served as the basis for other bilateral treaties, but was denounced in 1980 by then-Iraqi Vice President Saddam Hussein. The agreement, commonly known as the Algiers Agreement, was signed in 1975 and aimed to settle border disputes between Iran and Iraq. It served as a roadmap to improve relations between the two countries. After the Baath Party controlled the government, Iraq demanded in 1968 full control of Shatt al-Arab (Arvand Rud).  On April 19, 1969, Iran withdrew from the 1937 agreement signed between Iraq and Iran to resolve border issues, arguing that Iraq was imposing Iranian boats in the Shatt al-Arab.  In April 1969, both armies were deployed on the shores of the Persian Gulf. After Iran took control of four islands in the Persian Gulf, diplomatic relations between Baghdad and Tehran deteriorated significantly.  Iraq encouraged the Arabs of Khuzestan to rebel against the Shah of Iran Mohammad Reza Pahlavi.
Iraq has also driven all Iranians out of Iraq.  Iran supported the Kurds in the Iraqi-Kurdish war with military equipment and funding. Mustafa al-Barzani met with US government officials to secretly support the Kurds, further weakening the Iraqi position, made even more complicated by the outbreak of the Yom Kippur War. Iraq has now had to appease Iran, fearing that Iran would attack it from the east, while most Iraqi forces were fighting on the Syrian front.  The reorganisation of the territory by modern techniques is one of the objectives of the renewed agreement. The agreement signed here invited the foreign ministers of the two countries to meet in Tehran, the Iranian capital, to prepare a controversial border demarcation by a joint commission. “I am pleased to announce,” said the President, “that an agreement was signed last night to completely eliminate the conflict between the two brotherly countries, Iran and Iraq.” In 1963, after the Ramadan Revolution, the Baath Party government led by Ahmad Hassan al-Bakr launched a campaign against the Kurdish rebellion that aimed at Iraq`s independence. . .
