My country is USA.Currently,The USA is the powerest country in the world.
In the start of the World War I, USA did not participate. It just played the seller in the War. Firstly, The main reason of the WWI, Imperialist countries political and economic development imbalance, because the capitalist countries such as Germany after the second industrial revolution, military, economic, national strength enhanced greatly. Then Germany wanted to conquser the world. The country of Austro-Hungary invaded Serbia. Then Germany helped Austro-Hungary to conqusered Serbia. Beause the Russia was too close to Serbia. They knew the Goal of the Germany, so helped with Serbia and joined WWI. On the west front. The famous battle in verdun. It was called “Most devastating battle”. 1 million people Casualty. USA just supplied the weapon, goods, materials to France and british. The U.S was very smart. They only need to wait the gain from the War. Until almost end the war. Germany new submarine U-Boat sank the British liner Lusitania in 1915,with 128 Americans. And the Germany send a confidential to Mexico and invited them to joined the war. Unfortunately, The US stolen the confidential. And US joined the entente countries. In order to protect U.S. investors and the federal government's substantial investment in Europe is one of the main reason for America's war.Let the entente got victory in the World War I.
After the World War I, especially, the USA was the biggest winner in the war. They developed the domestic economic and gradually stronge in the World. During the World War II. The USA use the same method. They did not enter the War in the start, just became a providor and supply the material and weapon to the western European countries while they researching and studying the nuclear weapon. The project name’s manhattan project.The time was almost end the war. Then on the pacific ocean Japan attacked the Pearl Harbour. This event that US real joined the WWII. And US successful study of atom bomb. In Augest 6,1945. The first atom bomb by human being bombing in Hiroshima, It caused hundred and forty thousand people died. Then in Augest 8,1945. US were bombing the second atom bomb in Nagasaki. End of the war, The original Big countries such like Britain, France and German. They during the WWI and WWII were cause side-effect. They cannot be at a stalemate with US. US got the gain from them. US rapid developed economic and become the one of the biggest and strongest chounty.
After WWI and WWII, the time entered post war. The mainly countries were US and USSR. NATO and Warsaw pact the establishment of international organizations, and marks the official start of the military confrontation, both sides in the form of the cold war. The mainly change in the world was Soviet Union dissolution. The mian reason was One-party rule, or bright or dark purges, often in two post-war pursues power chauvinism, especially the invasion of Afghanistan in the 80 s, but also caused a scandal in the world, the armed occupation of Hungary, and so on. In fact, the Soviet union has lost the support of the socialist bloc countries. Economically, starting from the Soviet union was founded, the country's center of gravity in the industry, due to the start of the cold war after WWII, make the economic system of the Soviet union more extreme, industry are almost for military service, people's food and clothing problems frequently occur, combined with European and American capitalist countries economic offensive, the disintegration of the Soviet economy in before has virtually collapsed, gorbachev's reforms just let this contradiction.Militarily, the Soviet union and the United States great consumes the national strength of the cold war, the Soviet union's military is not on democracy, but in the suppression of democratic and invasion of other countries. Against Yugoslavia, and China have deteriorated and chauvinist ideology overflow, the failure of the war in Afghanistan has hit the Soviet power.
