Bill O'Reilly Says His Warning to Trump About Iran War Haunts Him

Former Fox News host Bill O'Reilly told NewsNation that a private conversation with President Donald J. Trump in February 2026, just hours before the United States launched military action against Iran, now haunts him. He warned Trump that attacking Iran would be "the biggest gamble" of his life, likening Iranian militants to those of World War II and saying a direct strike would be extremely difficult and could spark widespread anti‑American sentiment.

O'Reilly said he urged Trump to pursue diplomatic and economic pressure rather than conventional strikes, and he recalled his own regret over the Iraq‑war miscalculations. As the Iran conflict continues, he repeated that his words "exactly how it came down" and that the consequences he warned about are unfolding, leaving him haunted by the advice he gave.
