The building bombed in Mission: Impossible – Ghost Protocol is the Kremlin. Ethan Hunt’s IMF team infiltrates the Moscow landmark while investigating “Cobalt,” but their cover is exposed and a bomb destroys the building as they escape.
The bombing is part of a larger deception. Kurt Hendricks, the extremist known as Cobalt, arranges the attack to conceal his theft of a Russian nuclear-launch-control device. Because the IMF is publicly blamed, the organization is disavowed under the film’s “Ghost Protocol,” leaving Hunt and his team without official support.
The Kremlin is Russia’s fortified government complex in central Moscow, best known for its palaces, cathedrals, museums, and association with the Russian state. A common mix-up is to remember the later nuclear threat rather than the location: the missile is ultimately aimed at San Francisco, but the building destroyed earlier is the Kremlin. The Reichstag, Louvre, and Pentagon are not the bombed site in this film.
