A senior U.S. Army officer has been removed from his position within the Joint Chiefs of Staff after it was discovered that he authored a series of inflammatory and anti-Israel posts on social media under a semi-anonymous account, defense officials confirmed.
Col. Nathan McCormack, who served as the Levant and Egypt branch chief in the Joint Staff’s J5 Strategic Planning Directorate since June 2024, was reassigned pending further investigation.
His posts, which included accusations against Israel and the U.S.-Israel alliance, were made under a now-deleted X (formerly Twitter) account which JBN has obtained archived copies of.
