Israel was reinstated in 1948, shortly after the end of World War II, especially after the need for an independent state for Jews was highlighted by the Holocaust.

The European Economic Community was founded in 1957 by the Treaty of Rome. It may be understood as one of a few precursor organizations to the later European Union. All of these countries were founding members except Great Britain.

Although the Western Powers and Japan opposed the Bolsheviks during the Russian, one by one they decided to establish relations with the Soviet Union once the Bolshevik victory became clear. Some countries, such as Great Britain, hoped to improve trade with the Soviet Union, while others, such as Germany, established diplomatic relations because they shared mutual resentment of the victorious allies with the Soviet Union. Most countries established relations with the Soviet Union in the 1920s. The United States was an exception, since it did not recognize the Soviet government until 1933. The delay in recognition was partially due to the strong anti-communist movement in the United States, and partially due to Russia's relative unimportance to America as a trade partner.

The state of Israel was founded by a resolution of the United Nations. After the end of the Second World War, increasingly large numbers of Jewish settlers came to settle in Palestine. Sectarian violence between the Jewish and Arab populations escalated and Britain turned the authority of settling the Palestinian situation to the United Nations. In a UN resolution it was decided that British Palestine would be divided into a majority Muslim country and a majority Jewish country - thus creating the state of Israel.

The Warsaw Pact was created in the 1950s in reaction to the growth of NATO (particularly the admittance of West Germany into NATO in 1955). The Warsaw Pact was the Eastern European, communist equivalent of the North Atlantic Treaty Organization in Western, capitalist Europe.

The League of Nations was the brainchild of American President Woodrow Wilson, yet the United States never joined the League. This is because Congress failed to ratify the treaty which would have led to America’s participation. Lack of American involvement is one of the many reasons why the League of Nations would ultimately prove so ineffective.

The Ottoman Empire collapsed in 1922 after World War I, and Turkey was recognized as a republic a year later. The Ottomans are regarded as one of the great empires, arguably peaking in the 1400s with the capturing of the Byzantine empire's capital Constantinople. Turkey established a new Constitution in 1924 and several steps towards secularizing the country were taken.

Woodrow Wilson’s Fourteen Points were issued in the wake of the First World War and were designed to ensure global peace and prosperity and prevent the outbreak of future global conflicts. His Fourteen Points included all of the aforementioned except the creation of the European Union, which was an idea that emerged in the wake of the atrocities of the Second World War.

The Treaty of Versailles included all of the aforementioned provisions except that Italy took control of the Tyrol from Austria rather than from Germany. The modern-day Tyrol continues to be partially a part of Italy and partially a state in Austria.

All of these countries were members of the North Atlantic Treaty Organization except Poland which was one of the founding members of the eastern bloc and the Warsaw Pact.
