Under the leadership of Chancellor Helmut Kohl and Kinkel, the German Bundestag in 1993 agreed on a three-point amendment to the 1949 Constitution that for the first time let German troops take part in international peacekeeping operations sanctioned by the United Nations and other bodies, subject to advance approval by parliament. Shortly after, the German Parliament approved a controversial troop deployment under the umbrella of the United Nations Operation in Somalia II, clearing the final hurdle for what was then Germany's biggest deployment of ground forces abroad since World War II. Also under Kinkel’s leadership, Germany began destroying stockpiles of tanks and other heavy weapons in the early 1990s, becoming the first country to implement the Treaty on Conventional Armed Forces in Europe.
