Operation Beit ol-Moqaddas

The operation was a success, as it achieved its standing aim of liberating Khorramshahr and pushed Iraqi troops back to the border.

On 22 September 1980, because of threats from Khomeini's regime, leading to the abrogation of the 1975 Algiers Agreement, Iraqi President Saddam Hussein declared war against Iran and launched a land invasion of southern Iran, although operations did occur elsewhere on the Iran–Iraq border.

After achieving successes due to the post-Revolution military and political chaos in Iran, Saddam Hussein ordered that the Iraqi troops "dig-in" on the front line.

He hoped that this would show the world that he cared about the fate of the Iranian people, and that he was only concerned with achieving his aim of securing the entire Shatt al-Arab waterway, which had been resolved since the 1975 Algiers Agreement, but was disputed again since the treaty was abrogated due to Iran's actions.
