Analysis of information sources in references of the Wikipedia article "Iraqi invasion of Iran" in English language version.
There remains the issue of sovereignty over Shatt al-Arab. ... Granted that this might have been a genuine motive for abrogating the 1975 treaty, and reclaiming title to the whole Shatt, what was the point of the invasion on September 22? Iraq had taken back by unilateral action on September 10 the only strips of territory it still claimed under the treaty. There was no longer any 'territory' as such on the other side to conquer. The Ba'th had already followed the Shah's example of 1971 when he unilaterally took over the three islands in the Gulf.
