During the 20th century America has had its ups and downs in accordance to power, however in my judgement I feel the main influence on their power was their impact in the Second World War. In the run up to the Second World War America showed their power, in a fashion, by being an independent country. They refrained from being involved in the sales of arms to foreign bodies and they kept to the idea of being an isolationist country.
After the First World War the American government voted that it was going to become an isolationist country, this meant they would keep out of any foreign affairs that would come up in the future. Even though the German forces were moving into the surrounding countries.

Up until this point America had shown their power by keeping themselves out of the war, showing that they were not scared of Hitler. However by performing this lending act to the British forces Roosevelt shows that he fears for what might happen if America does not aid the allied forces. Roosevelt appeared to only be lending weapons to the allied forces and not the axis which would have shown to Hitler that he had implicated which side he was on.
Most people say that the main reason for America joining WW2 was the Japanese bombing on Pearl Harbour. Pearl harbour took place on 7th December 1941, when Japanese suicide bombers rained havoc on American gun ships. The attack consisted of two aerial attack waves consisting of 353 aircraft which were situated on 6 Japanese aircraft carriers. After the attack on Pearl Harbour America declared war on only Japan and not Germany as they had no real reason for joining the allied forces. A few days later however Hitler declared war on America, giving them a way out of the dilemma of whether or not to join the war. I feel the attack on Pearl Harbour gave America a chance to show their real power as they had a hugely sophisticated military basis and a very intelligent government. This showed throughout WW2 as they managed to overcome the German and Japanese forces along with the other allied forces.
After WW2 America became the most powerful country in the world, they became much more powerful than they had been in the past. It is also their most powerful position as circumstances in years to come left America in a much less powerful state. America was owed money from most of the country’s that were involved in the war, including England. All the money that was coming in to the US gave their economy a huge boom.
