Gulf War fallout
As stated before Iraq never really accepted the border between Iraq and Kuwait. Then in mid July of 1990 Saddam accused Kuwait of stealing billion dollars worth of Iraqi oil on fields on the border. Iraq needed all the money it could get to rebuild after its involvement in the Iran Iraq war (1 ).
Tensions rose between the two countries
On late July of 1990 Saddam summoned US ambassador April Glaspie to his Palace, it was an unusual move. This was after the US announced it doing joint United Arab Emirates (2 ). MS Glaspie seem to repeat what at been American policy towards Iraq, till then, she said "we have no opinion on . . . your border disagreement with Kuwait.". when asked about the Kuwait Iraq crisis (3 ).
So Saddam invaded Kuwait on 2 August 1990, this conflict end on 28 February 1991 after American coalition forces intervened. This is the aftermath of this intervention
oil for food/UN sanctions
Members of an international team of health experts visited Iraq in August and September of 1991, it found that four times as many children are dying as before the Gulf War. One million were malnourish and water borne disease was rampant. UN resolutions 706 and 712, allowed oil sales for purchase of food and medicine. Iraq rejected both of these. A UN Staffer said about these resolutions "[T]he US intention was to present Saddam Hussein with so unattractive a package that Iraq would reject it and thus take on the blame, at least in Western eyes, for continued civilian suffering."(4 ).
In January 1996 Saddam agreed to discuss the terms under which Resolution 986(oil for food res.) implemented. By August the Security Council's 661 Sanctions Committee endorsed the scheme. Of the 2 billion worth of oil sold by Iraq every six months.
