Cato's non-interventionist foreign policy views, and strong support for civil liberties, have frequently led Cato scholars to criticize those in power, both Republican and Democratic. Cato scholars opposed President George H. W. Bush's 1991 Gulf War operations (a position which caused the organization to lose nearly $1 million in funding), President Bill Clinton's interventions in Haiti and Kosovo, President George W. Bush's 2003 invasion of Iraq, and President Barack Obama's 2011 military intervention in Libya. As a response to the September 11 attacks, Cato scholars supported the removal of al Qaeda and the Taliban regime from power, but are against an indefinite and open-ended military occupation of Afghanistan. Cato scholars criticized U.S. involvement in Saudi Arabian-led intervention in Yemen.
