Despite the strong relationship between the two countries, opinion polls between the two nations show negative feelings between the American people and Saudi people in recent years, particularly American feelings towards the desert kingdom. Most American criticism pertains to lack of human rights in Saudi Arabia and the alleged role Saudi Arabia played in the September 11 attacks. A poll of Saudis by Zogby International (2002) and BBC (between October 2005 and January 2006) found 51% of Saudis had hostile feelings towards the American people in 2002; in 2005–2006, Saudi public opinion was sharply divided with 38% viewing U.S. influence positively and 38% viewing U.S. influence negatively. As of 2019, Saudi Arabian students form the 4th largest group of international students studying in the United States, representing 3.4% of all foreigners pursuing higher education in the U.S. A December 2013 poll found 57% of Americans polled had an unfavorable view of Saudi Arabia and 27% favorable.
