 On April 16, 1975, the US Army renamed the building the General Creighton W. Abrams Building.The renaming did not have full authority in law, because the US was technically leasing the building from the German government and thus was not the rightful owner.On May 11, 1972, three bombs were set off by the West German terrorist group "Rote Armee Fraktion" (Red Army Faction, i.e., the Baader-Meinhof Group).
