At the 18th Independent Spirit Awards in 2003, she spoke out against the Iraq war, stating the reason for the invasion was "oil and imperialism". In 2005, Gyllenhaal drew controversy for her statement that the September 11 attacks were "an occasion to be brave enough to ask some serious questions about America's role in the world  ... It is always useful as individuals or nations to ask how we may have knowingly or unknowingly contributed to this conflict." Gyllenhaal took part in Artists United to Win Without War, a campaign started by Robert Greenwald that aimed to advance progressive causes and voicing opposition to the Iraq War.
