The court also ruled that when military targets were concentrated in a comparatively small area, and where defence installations against air raids were very strong, that when the destruction of non-military objectives is small in proportion to the large military interests, or necessity, such destruction is lawful. Thus, in the judgement of the Court, because of the immense power of the atom bombs and the distance from enemy (Allied) land forces, the atomic bombings of both Hiroshima and Nagasaki "was an illegal act of hostilities under international law as it existed at that time, as an indiscriminate bombardment of undefended cities".
