The phrase has also come to be used in describing any situation infused with a sense of impending doom, especially when the peril is visible and proximal—regardless of whether the victim is in a position of power. US President John F. Kennedy compared the omnipresent threat of nuclear annihilation to a sword of Damocles hanging over the people of the world. Soviet First Secretary Nikita Khrushchev wanted the Tsar Bomba to "hang like the sword of Damocles over the imperialists' heads".
