Drezner rarely discusses his political loyalties, but in 2011 he wrote: "I find liberals write 'even conservative Dan Drezner..' while conservatives often deploy terms like 'academic elitist' or 'RINO.'
Drezner supported the 2003 U.S. invasion of Iraq, writing that "a successful invasion not only eliminates the Iraqi threat, but over the long run it reduces the Arab resentment that feeds Al-Qaeda."
