Dreher has been a consistent critic of the role of Islam in international affairs, but has shifted in his view of the efficacy of foreign military interventions. Subsequent to the September 11 attacks, Dreher published numerous articles that were critical of Islam, including one in which he praised the Italian anti-Islamic writer Oriana Fallaci's book, "The Rage and the Pride", as containing "much truth" to "shock awake a noble civilization hypnotized by multiculturalist mumbo-jumbo"; he also noted that the book contained a "few ugly parts". Fallaci's book has been described as exhibiting "extremely blatant racism" by the Canadian scholar Sherene Razack. In 2002, Dreher described the assassinated Dutch anti-Islamic politician Pim Fortuyn as a "martyr in the war on political correctness." Dreher supported the Iraq War in 2003, but later came to believe that the invasion was a mistake; he now supports a non-interventionist foreign policy. He was critical of US President Donald Trump's decision to order missile strikes in Syria in April 2017.
