How and why did the US get involved in World War 2?

At first, sentiment in America was strongly against involvement in the European conflagration. Americans wanted to remain free of the struggle between Europe�s great powers. Neutrality was the nation�s keynote.

But there were events that America could not control. A German submarine sank the liner Lusitania in 1915, killing 128 Americans in the process. But America refused to declare war on Germany. In 1916 President Wilson was reelected President of the United States on the slogan, �He kept us out of war.�

The following year the Germans announced that all shipping, whether belligerent or neutral, would be fair game to their submarines. This meant that American ships were no longer safe on the high seas. Seemingly, it left Wilson with no alternative. He reluctantly declared war on Germany, stating: �It is a fearful thing to lead this great peaceful people into war, into the most terrible and disastrous of all wars, civilization itself seeming to be in the balance.�

Wilson was so convinced of having God�s backing in his project that he insisted on attending the Paris Peace Conference in 1919�this in spite of the fact that many political friends thought that the President of the United States should remain independent of the peace negotiations. He believed that he had the people of the world behind him even if he did not have all the politicians. He was convinced that he was God�s instrument for peace. He, more than anyone else, had to go to Paris.

Neutrality was over, America was now embroiled in the worst war that man had known until then.

AnswerThe Us get involved in World War Two due to the Japanese bombing Pearl Harbour Answerthe main reason the united states entered WWII is not becaue of the pearl harbor bombin but becasue FDR was afriad that the Nazi Party would reach the United States and he wanted to stop them. Then Pearl Harbor was bombed and he had no choice put to go to war. AnswerWhen Japan attacked Pearl Harbor, USA's main Naval harbor, much of their Naval fleet was sunk. There was no main reason for the Japanese to attack Pearl Harbor, except of course to prevent future attacks...This, of course, made the USA very mad, and already considering joining the battle in Europe to help out Britain, this was just the last straw. The US then sent troops to the Philippines and towards Japan, and into Europe to help defeat Germany. Answer12/7/41 (two years in) Japan attacked Pearl Harbor from the air.
