"A Saudi Arabia-backed plan to end the war agreed to by Iraq included $70 billion in war reparations to be paid by Arabian states of the Persian Gulf on behalf of Iraq, and complete the Iraqi evacuation from Iranian territory - an offer called by some critics of Iranian government as "extraordinarily favorable to Iran."[36] Iran rejected Iraq's offer, demanding the removal of the Saddam Hussein regime, the repatriation of 100,000 Shi'ites expelled from Iraq before the war, and $150 billion in war reparations.[citation needed]
On 21 June, Khomeini indicated that Iran would invade Iraq shortly, and on 22 June, the Iranian Chief-of-Staff Shirazi declared to "continue the war until Saddam Hussein is overthrown so that we can pray at Karbala and Jerusalem".[30] This matched a comment made by Khomeini on the issue of a truce with Iraq: "There are no conditions. The only condition is that the regime in Baghdad must fall and must be replaced by an Islamic Republic."[37]"
