A senior U.S. military official, McCormack, deleted his semi-anonymous X (formerly Twitter) account after controversial posts criticizing the U.S.-Israel relationship came to light. McCormack served in a critical role within the J5 directorate of the Joint Chiefs of Staff, where he advised the chairman on strategic military planning and international security matters. His duties included preparing top military leaders for diplomatic engagements, especially with partner nations like Israel. Posting under the alias “Nate,” McCormack frequently referenced his job and even displayed his Meritorious Service Medal, underscoring his high-level clearance and influence. Since assuming his role in June 2024, he posted regularly about Israel, particularly following the Hamas attack on October 7.

His posts attracted widespread attention for their harsh criticism of both Israel and U.S. foreign policy. In April, McCormack claimed that Western governments refrained from criticizing Israel due to “Holocaust guilt,” while in May, he accused Israeli Prime Minister Benjamin Netanyahu and his “Judeo-supremacist cronies” of prolonging the conflict for political advantage. He further questioned whether the U.S.-Israel alliance had devolved into a proxy relationship, potentially operating without full awareness from U.S. leadership. Given his involvement in sensitive defense planning, these remarks have sparked intense backlash and concern. The revelation of his identity and his sudden account deletion have raised alarms within military and diplomatic communities, prompting the Pentagon to evaluate the broader consequences of his statements on U.S. strategic credibility and international partnerships.
