Pete Hegseth, who recently assumed the role of U.S. Defense Secretary, has previously made extensive public statements characterizing Iran as a significant threat to American interests, according to a review of his past writings and media appearances.

In his 2020 book, Hegseth wrote that Iran's leaders were "actively seeking the military means – especially nuclear weapons – to bring the West to its knees." He has also described Iran as "America's mortal enemy" in a 2017 educational video produced for PragerU, a conservative media platform.

These statements were made during Hegseth's previous career as a Fox News host and author, before his appointment to lead the Pentagon. His comments appeared across various platforms including books, television broadcasts, educational videos, and a 2018 speech delivered at an Israeli media conference in Jerusalem.

Hegseth's appointment as Defense Secretary brings his previous public positions into focus as he now oversees the world's largest military. His past statements suggest a hawkish stance toward Iran, which has been a point of tension in U.S. foreign policy across multiple administrations.

The Defense Department has not issued statements clarifying how Hegseth's previous commentary might influence current policy approaches toward Iran or other Middle Eastern matters.
