19 14, the first world war broke out; 19 17, the United States was involved in the whirlpool of war and tried to play a new role in the world.
From 65438 to 0929, the Great Depression of capitalism occurred, which affected not only the United States, but also all countries in the world. The economic panic caused millions of workers to lose their jobs, a large number of farmers were forced to give up their farmland, factories and shops closed, banks closed down and there was a depression.
1932, franklin roosevelt (1882 ~ 1945) was elected president, and fully implemented the "Roosevelt New Deal" with government intervention in the market as the main means. He advocated that the government should take action to end the economic panic, and then launched a series of policies to temporarily solve many difficulties, but the American economy did not wake up until after World War II.
1939, World War II broke out. 194 1 65438+February 7, 2008, after Japan attacked Pearl Harbor, the United States entered the war and became the main force in the Pacific battlefield.
After World War II, with the defeat of the Axis countries and the decline of the strength of Britain and France, the United States and the Soviet Union became superpowers, and the world was divided into two camps: East and West. The United States and the Soviet Union and their respective camps confronted each other in an all-round way in military, political, economic, propaganda and other aspects, just like wartime, which is called the "Cold War" in history.
1950, the Korean War broke out, and the US military entered the war and fought side by side with the newly established People's Republic of China (PRC) Volunteers. The two sides of the war finally signed an armistice agreement with the 38th parallel as the boundary. After the war, the cold war escalated gradually.
From 65438 to 0962, the Cuban missile crisis pushed the panic caused by the Cold War to its peak. 1969, Apollo 1 1 put a man on the moon for the first time, and the United States gradually surpassed the Soviet Union in the space race.
In the mid-1960s, when the Vietnam War broke out, many Americans began to be dissatisfied with the government's foreign policy, and anti-war demonstrations were accompanied by various civil rights movements. In addition, due to the development of industry and the concentration of population, the pollution of ecological environment was widely concerned in the late 1960 s, and the economic depression caused by the energy crisis was the most serious in history in the early 1970 s. In the mid-1970s, the American economy once recovered, but in the late 1970s, inflation reappeared.
1976, the bicentennial of the founding of the United States, various celebrations were held all over the country. Because of its comprehensive advantages in global politics, military affairs, economy and highly developed science and technology, the United States finally brought down the Soviet Union in the Cold War, and the Soviet Union disintegrated at 199 1, and the United States won the final victory in the Cold War. The bipolar pattern has gradually been replaced by the new international situation of more than one superpower, and the United States has become a superpower.
Extended data:
The United States has global economic, political and military influence, and its foreign policy trend has always been the focus of world attention and discussion. The scale of American diplomatic relations is the largest in the world. Almost all countries have embassies and ambassadors in DC.
In the western world, Britain, Canada and Australia are all regarded as America's closest allies. In Asia, after World War II, Japan, the Republic of Korea and Israel all had very close diplomatic relations with the United States, and even American troops were stationed in Japan and South Korea (see US troops stationed in Japan and US troops stationed in South Korea).
At present, only North Korea, Iran, Syria and Bhutan have no diplomatic relations with the United States. 20 15 After then US President Barack Obama visited Cuba, Cuba and the United States resumed diplomatic relations that had been interrupted for more than 50 years.
However, the diplomacy of the United States in the Middle East and Islamic society after the Cold War has been regarded as a failure all the year round, and it has been deadlocked since the Palestinian-Israeli issue, and then from the 9 1 1 incident to the quagmire of wars in Afghanistan and Iraq. The Arab Spring has turned into the Arab Winter, and the situation in Libya, Syria, Egypt and Lebanon, which experienced turmoil, has not yet stabilized, leading to the intensification of anti-American waves in more than 20 countries in the Middle East.
And American foreign policy is really elusive. According to relevant data, the US government is well aware of the threat of terrorist organizations, and it still leaves it alone, which has led to the intensification of the threat of the "Islamic State" to the Middle East.
