Saddam's primary interest in war may have stemmed from his desire to right the supposed "wrong" of the Algiers Agreement, in addition to finally achieving his desire of annexing Khuzestan and becoming the regional superpower. Saddam's goal was to replace Egypt as the "leader of the Arab world" and to achieve hegemony over the Persian Gulf. He saw Iran's increased weakness due to revolution, sanctions, and international isolation. Saddam had invested heavily in Iraq's military since his defeat against Iran in 1975, buying large amounts of weaponry from the Soviet Union and France. Between 1973 and 1980 alone, Iraq purchased an estimated 1,600 tanks and APCs and over 200 Soviet-made aircraft. By 1980, Iraq possessed 242,000 soldiers (second only to Egypt in the Arab world), 2,350 tanks and 340 combat aircraft. Watching the powerful Iranian army that frustrated him in 1974–1975 disintegrate, he saw an opportunity to attack, using the threat of Islamic Revolution as a pretext.
