<P0-S0> the composition of the council was changed several times. <P0-S1> the number of non-permanent members was first increased to six on 22 september 1922 and to nine on 8 september 1926. werner dankwort of germany pushed for his country to join the league; joining in 1926, germany became the fifth permanent member of the council. <P0-S2> later, after germany and japan both left the league, the number of non-permanent seats was increased from nine to eleven, and the soviet union was made a permanent member giving the council a total of fifteen members. <P0-S3> the council met, on average, five times a year and in extraordinary sessions when required. <P0-S4> in total, 107 sessions were held between 1920 and 1939. <SEP> <P1-S0> The Molotov -- Ribbentrop Pact, also known as the Nazi -- Soviet Pact, the German -- Soviet Non-aggression Pact or the Nazi German -- Soviet Pact of Aggression (officially: Treaty of Non-aggression between Germany and the Union of Soviet Socialist Republics), was a neutrality pact between Nazi Germany and the Soviet Union signed in Moscow on 23 August 1939 by foreign ministers Joachim von Ribbentrop and Vyacheslav Molotov, respectively. <P1-S1> The pact was followed by the German - Soviet Commercial Agreement in February 1940. <SEP> <P2-S0> The Soviet Union suffered greatly in the war, losing around 27 million people. <P2-S1> Approximately 2.8 million Soviet POWs died of starvation, mistreatment, or executions in just eight months of 1941 -- 42. <P2-S2> During the war, the Soviet Union together with the United States, the United Kingdom and China were considered as the Big Four of Allied powers in World War II and later became the Four Policemen which was the foundation of the United Nations Security Council. <P2-S3> It emerged as a superpower in the post-war period. <P2-S4> Once denied diplomatic recognition by the Western world, the Soviet Union had official relations with practically every nation by the late 1940s. <P2-S5> A member of the United Nations at its foundation in 1945, the Soviet Union became one of the five permanent members of the United Nations Security Council, which gave it the right to veto any of its resolutions. <SEP> <P3-S0> During the Middle Ages, the Eritrea region was known as Medri Bahri ("sea-land"). <P3-S1> The name Eritrea is derived from the ancient Greek name for Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa, based on the adjective ἐρυθρός erythros "red"). <P3-S2> It was first formally adopted in 1890, with the formation of Italian Eritrea (Colonia Eritrea). <P3-S3> The territory became the Eritrea Governorate within Italian East Africa in 1936. <P3-S4> Eritrea was annexed by Ethiopia in 1953 (nominally within a federation until 1962) and an Eritrean Liberation Front formed in 1960. <P3-S5> Eritrea gained independence following the 1993 referendum, and the name of the new state was defined as State of Eritrea in the 1997 constitution. <P3-S6> [citation needed] <SEP> <P4-S0> As of 29 February 2016, 124 countries were contributing a total of 105,314 personnel in Peacekeeping Operations, with Ethiopia leading the tally (8,324), followed by India (7,695) and Bangladesh (7,525). <P4-S1> In June 2013. <P4-S2> Pakistan contributed the highest number overall with 8,186 personnel, followed by India (7,878), Bangladesh (7,799), Ethiopia (6,502), Rwanda (4,686), Nigeria (4,684), Nepal (4,495), Jordan (3,374), Ghana (2,859), and Egypt (2,750). <P4-S3> As of 28 February 2015, 120 countries were contributing a total of 104,928 personnel in Peacekeeping Operations, with Bangladesh leading the tally (9446). <P4-S4> As of March 2008, in addition to military and police personnel, 5,187 international civilian personnel, 2,031 UN Volunteers and 12,036 local civilian personnel worked in UN peacekeeping missions. <SEP> <P5-S0> israel has one of the highest ratios of defense spending to gdp of all developed countries, only topped by oman and saudi arabia. <P5-S1> in 1984, for example, the country spent 24% of its gdp on defense. <P5-S2> by 2006, that figure had dropped to 7.3%. <P5-S3> israel is one of the world's largest arms exporters, and was ranked fourth in the world for weapons exports in 2007. the majority of israel's arms exports are unreported for security reasons. <P5-S4> since 1967, the united states has been a particularly notable foreign contributor of military aid to israel: the us is expected to provide the country with $3.15 billion per year from 2013 to 2018. israel is consistently rated low in the global peace index, ranking 148th out of 162 nations for peacefulness in 2015.
