Answer:
D. He believed Kuwait was responsible for low oil prices.
Step-by-step explanation:
The answer is complicated. While it is true that Iraq claimed Kuwait was a part of Iraq, taken away by the Brittish during the Anglo-Ottoman Convention, the main reason for war was Economic. Iraq had a significant debt with Kuwait. Kuwait helped Iraq during the Iran-Iraq war, and Iraq owed Kuwait a large sum. However, oil prices remained low al through the 1980s, and Irak blamed Kuwait, as the Emirate did not want to lower production to spike up prices.
Then, as a cause of war, Iraq claimed that Kuwait was stealing oil from Iraq by using slant drilling.
