Justin Yifu Lin is a Chinese economist who is the author of the book "The Quest for Prosperity: How Developing Economies Can Take Off".
In his papers, Lin describes how the China, which many centuries ago was forced to enter a trade with Great Britain after the Opium Wars and was solely seen as a sourcing point, now faces a completely different reality in regards to commercial relations with the British.
The Chinese, whose strength relies on their massive and relatively cheap labor force, understood that the key to development was in acquiring knowledge that would let them thrive in the creation of their own industries. This process has been ongoing throughout the second half of the 20th century until nowadays, as British Enterprises set operations in Chinese Soil, employing Chinese citizens who would eventually benefit from all the knowledge they received. This process has resulted in the creation and incredible growth of global enterprises such as Hayer or Huawei.
The Constitution of the United States divides the federal government into three branches to make sure no individual or group will have too much power:
Legislative—Makes laws (Congress, comprised of the House of Representatives and Senate)
Executive—Carries out laws (president, vice president, Cabinet, most federal agencies)
Judicial—Evaluates laws (Supreme Court and other courts)
Each branch of government can change acts of the other branches:
The president can veto legislation created by Congress and nominates heads of federal agencies.
Congress confirms or rejects the president's nominees and can remove the president from office in exceptional circumstances.
The Justices of the Supreme Court, who can overturn unconstitutional laws, are nominated by the president and confirmed by the Senate.
After then U.S. President Woodrow Wilson's failed attempts to negotiate an agreement with Germany to end the unrestricted attacks of German submarines on British ships the German Foreign Minister, in what came to be known as the Zimmerman Telegram, invited Mexico to join the war alongside Germany and offered to help Mexico recover the Texas, New Mexico and Arizona territories. The UK intercepted the telegram and passed the information along to President Wilson. America saw this invitation as an act of war and so in an effort to put an end to militarization from foreign opposition U.S. congress called for war on Germany on April 6th, 1917.
The great and all powerful Soviet Union, and then after 1949 the communist german party took controlled which was maintained by the United Soviet Socialist Republic (USSR). Also I should mention that the Allies wanted to split the city of Berlin up since it was fair.. So Berlin was split in 4 parts and thats why you hear the name "Berlin Wall" which was the Soviet Wall surrounding their side of the city..
