Given the question: Information:  - The North Atlantic Treaty Organization (NATO  '), also called the North Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defence in response to an attack by any external party. Three NATO members are permanent members of the United Nations Security Council with the power to veto and are officially nuclear-weapon states: the United States, France and the United Kingdom. NATO's headquarters are located in Haren, Brussels, Belgium, where the Supreme Allied Commander also resides. Belgium is one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22 countries participate in NATO's Partnership for Peace program, with 15 other countries involved in institutionalized dialogue programmes. The combined military spending of all NATO members constitutes over 70% of the global total. Members' defence spending is supposed to amount to 2% of GDP.  - The BonnParis conventions were signed in May 1952 and came into force after the 1955 ratification. The conventions put an end to the Allied occupation of West Germany.  - West Berlin was a city that existed in the period between the end of the Berlin Blockade on 12 May 1949 to German reunification on 3 October 1990 as a political enclave surrounded by East Berlin and East Germany. It was east of the Inner German border and only accessible by land from West Germany by narrow rail and highway corridors. It consisted of the American, British, and French occupation sectors established in 1945 and shared economic, political, legal, and sporting systems with West Germany, but was not "de jure" part of it. It had a special and unique legal status because its administration was formally conducted by the Western Allies. East Berlin, "de jure" occupied and administered by the Soviet Union, was the "de facto" capital of East Germany. The Berlin Wall, built in 1961, physically divided East and West Berlin until it fell in 1989.  - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux.  - East Germany, formally the German Democratic Republic or GDR, was an Eastern Bloc state during the Cold War period. From 1949 to 1990, it administered the region of Germany that was occupied by Soviet forces at the end of World War IIthe Soviet Occupation Zone of the Potsdam Agreement, bounded on the east by the OderNeisse line. The Soviet zone surrounded West Berlin, but did not include it; as a result, West Berlin remained outside the jurisdiction of the GDR. The German Democratic Republic was established in the Soviet Zone, while the Federal Republic was established in the three western zones. East Germany was a satellite state of the Soviet Union. Soviet occupation authorities began transferring administrative responsibility to German communist leaders in 1948, and the GDR began to function as a state on 7 October 1949. Soviet forces, however, remained in the country throughout the Cold War. Until 1989, the GDR was governed by the Socialist Unity Party (SED), though other parties nominally participated in its alliance organisation, the National Front of Democratic Germany.   - Weimar Republic is an unofficial, historical designation for the German state between 1919 and 1933. The name derives from the city of Weimar, where its constitutional assembly first took place. The official name of the state was still "Deutsches Reich"; it had remained unchanged since 1871. In English the country was usually known simply as Germany. A national assembly was convened in Weimar, where a new constitution for the "Deutsches Reich" was written, and adopted on 11 August 1919. In its fourteen years, the Weimar Republic faced numerous problems, including hyperinflation, political extremism (with paramilitaries  both left- and right-wing); and contentious relationships with the victors of the First World War. The people of Germany blamed the Weimar Republic rather than their wartime leaders for the country's defeat and for the humiliating terms of the Treaty of Versailles. However, the Weimar Republic government successfully reformed the currency, unified tax policies, and organized the railway system. Weimar Germany eliminated most of the requirements of the Treaty of Versailles; it never completely met its disarmament requirements, and eventually paid only a small portion of the war reparations (by twice restructuring its debt through the Dawes Plan and the Young Plan). Under the Locarno Treaties, Germany accepted the western borders of the republic, but continued to dispute the Eastern border.  - The Allied High Commission (also known as the High Commission for Occupied Germany, HICOG; in German "Alliierte Hohe Kommission", "AHK") was established by the United States of America, the United Kingdom, and France after the 1948 breakdown of the Allied Control Council to regulate and supervise the development of the newly established Federal Republic of Germany (West Germany). The Commission took its seat at the Hotel Petersberg near Bonn and started its work on September 21, 1949. It ceased to function under the terms of the BonnParis conventions, on May 5, 1955.  - The Warsaw Pact, formally the Treaty of Friendship, Co-operation, and Mutual Assistance and sometimes, informally, WarPac. was a collective defense treaty among the Soviet Union and seven other Soviet satellite states in Central and Eastern Europe in existence during the Cold War. The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the London and Paris Conferences of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe.  - The Occupation Statute of Germany ( German : Besatzungsstatut ) of April 10 , 1949 specified the roles and responsibilities of the newly created German government and the Allied High Commission in West Germany . It was drawn up by American , British , and French representatives and was in rule until the Treaties of Paris ( 1954 ) came into power on May 5 , 1955 . The statute 's authors were United States Secretary of State Dean Acheson , British Secretary of State for Foreign and Commonwealth Affairs Ernest Bevin , and the French Prime Minister Robert Schuman , who deliberated for eight days in intensive conferences in Washington , DC. It gave Germany conditional sovereignty and admitted it into the Marshall Plan organization as an equal partner . The Allies retained the right to keep occupational forces in the country and complete control over disarmament , demilitarization , related fields of scientific research , war reparations , the Ruhr , decartelization , displaced persons and refugees , protection , prestige and security of the occupying forces , foreign affairs , and foreign trade and exchange . The Allies ' representatives asked the Parliamentary council drafting a constitution to accept the statute . Although it met resistance from the SPD , the council accepted the Occupation Statute .  - The Cold War was a state of political and military tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period (the second half of the 20th century) between 1947, the year the Truman Doctrine (a U.S. policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed.  - The inner German border (or "deutsch-deutsche Grenze"; initially also "Zonengrenze") was the border between the German Democratic Republic (GDR, East Germany) and the Federal Republic of Germany (FRG, West Germany) from 1949 to 1990. Not including the similar but physically separate Berlin Wall, the border was long and ran from the Baltic Sea to Czechoslovakia.  - East Berlin existed between 1949 and 1990 and consisted of the Soviet sector of Berlin established in 1945. The American, British, and French sectors became West Berlin, strongly associated with West Germany, while East Berlin was the "de facto" capital of East Germany. From 13 August 1961 until 9 November 1989, East Berlin was separated from West Berlin by the Berlin Wall.  - The German reunification was the process in 1990 in which the German Democratic Republic (GDR/East Germany) joined the Federal Republic of Germany (FRG/West Germany) to form the reunited nation of Germany, and when Berlin reunited into a single city, as provided by its then Grundgesetz constitution Article 23. The end of the unification process is officially referred to as German unity, celebrated on 3 October (German Unity Day). Following German reunification, Berlin was once again designated as the capital of united Germany.  - West Germany is the common English name for the Federal Republic of Germany or FRG (or "RFA") in the period between its creation on 23 May 1949 to German reunification on 3 October 1990. During this Cold War era, NATO-aligned West Germany and Warsaw Pact-aligned East Germany were divided by the Inner German border. After 1961 West Berlin was physically separated from East Berlin as well as from East Germany by the Berlin Wall. This situation ended when East Germany was dissolved and its five states joined the ten states of the Federal Republic of Germany along with the reunified city-state of Berlin. With the reunification of West and East Germany, the Federal Republic of Germany, enlarged now to sixteen states, became known simply as "Germany". This period is also referred to as the Bonn Republic ("Bonner Republik") by historians, alluding to the interwar Weimar Republic and the post-reunification Berlin Republic.  - The Berlin Wall was a barrier that divided Berlin from 1961 to 1989. Constructed by the German Democratic Republic (GDR, East Germany), starting on 13 August 1961, the Wall completely cut off (by land) West Berlin from surrounding East Germany and from East Berlin until government officials opened it in November 1989. Its demolition officially began on 13 June 1990 and was completed in 1992. The barrier included guard towers placed along large concrete walls, which circumscribed a wide area (later known as the "death strip") that contained anti-vehicle trenches, "fakir beds" and other defenses. The Eastern Bloc claimed that the Wall was erected to protect its population from fascist elements conspiring to prevent the "will of the people" in building a socialist state in East Germany. In practice, the Wall served to prevent the massive emigration and defection that had marked East Germany and the communist Eastern Bloc during the post-World War II period.
