As global tensions continue to rise following recent strikes involving Iran, Israel, and the United States, many people have begun asking what would happen if a large-scale global conflict occurred. In extreme scenarios such as nuclear war, governments maintain detailed emergency procedures designed to ensure leadership continuity. According to security protocols known as the Continuity of Government Readiness Conditions (COGCON), the president would be evacuated quickly during a major national emergency.

If a crisis escalated, Donald Trump would likely first be transported by helicopter to a secure military location before being moved to the E‑4B National Airborne Operations Center, a specialized airborne command center capable of remaining operational during extreme situations. The aircraft, often described as a highly protected version of a Boeing 747, can stay in the air for extended periods with mid-air refueling.

From there, the president could later relocate to one of several hardened emergency facilities designed to protect government leadership. Possible locations include Mount Weather Emergency Operations Center, Raven Rock Mountain Complex (often called Site R), bunkers near Camp David, or other classified sites. These facilities are designed to maintain communication, military coordination, and national leadership during catastrophic emergencies.

At the same time, other government leaders, including the vice president and senior officials, would also be moved to secure locations to preserve the presidential line of succession. While such plans exist as precautionary measures, experts emphasize that nuclear weapons are primarily intended as deterrents, and global leaders generally work to prevent conflicts from escalating to that level.
