On 25 July 1990, the U.S. Ambassador to Iraq April Glaspie asked the Iraqi high command to explain the military preparations in progress, including the massing of Iraqi troops near the border.
The American ambassador declared to her Iraqi interlocutor that Washington, “inspired by the friendship and not by confrontation, does not have an opinion” on the disagreement between Kuwait and Iraq, stating "we have no opinion on the Arab-Arab conflicts".
She also let Saddam Hussein know that the United States did not intend "to start an economic war against Iraq". These statements may have caused Saddam to believe he had received a diplomatic green light from the United States to invade Kuwait.[24][25]
According to Richard E. Rubenstein, Glaspie was later asked by British journalists why she had said that, her response was "we didn't think he would go that far" meaning invade and annex the whole country. Although no follow-up question was asked, one might assume that what the U.S. government thought in July 1990 was that Saddam Hussein was only interested in pressuring Kuwait into debt forgiveness and to lower oil production.
