The US had already been involved with one European embroilment during the 1st World War (originally called the Great War, prior to WW2); and didn't relish the idea of another one. Germany/Japan may have attacked other nations; but they weren't attacking the US. Of all of the MAIN combatants, the US was the most geographically isolated from aggression (the Americas-North America, Central America, South America...of which the latter two remained neutral through out the war).
Politics, and finance.
All politicians have at least to considerations that guide their votes: 1st how will my vote enhance, or damage my ability to be re elected! Thus the mood of the public dictates when a democracy declares war. The sinking of the Lusitania, was the fuse that angered the American public against the Germans, this made it democratically safe to declare war against the Germans. Any government that gets it's country into an unpopular war, is domed to failure.
2nd Other peoples wars make wonderful markets, prophets for the rich, work for the people. When the country's children have to be armed to fight; this takes a large bight out of the national prophet margin. That is the bottom line, "Wars that are not prophet able are doom, for both the country, and the political party that declared them. The law of "U nighted we stand; Divided we fall" is the rule of thumb for declaring wars!
The Great Depression kept us initially from the war because of financial issues. Also, a fear of a WWI repeat with many lives lost was looming...A more in-depth look would point towards the Monroe Doctrine and keeping away from European affairs. All in all, the U.S. made money from not being in the war (the Land-Lease Act). This profit, many believe, is the reason the U.S. was brought out of the depression.
many Americans were isolationists.
Indeed, the short answer would be isolationist beliefs of many Americans (and congressmen)
There were many reasons but the most serious ones were : there was a world-wide depression going on, where over a quarter of the population was unemployed. Also, the government did not have the money to man and arm the armed forces , and the people of the US still had a "bad taste" from their experience with the First World War, which at the time, was billed as "The War to end all wars".
The general populace and the majority of the Congress did not want to fight in another European war after the fiasco of the Great War, World War 1. The US suffered the loss of too many men in a war fought for many convoluted reasons that had nothing to do the United States. They went to war out of anger over a few injustices that happened to them because of the European war but not for the reasons the Great War was being fought.
The Americans realized later they should have never gone to Europe to fight in that horrendous war. The European problems were not resolved in that war therefore when World War 2 started they refused to fight over European issues again.
Today's Americans and other people need to realize it was an age when people did not have cell phones, satellites, television, instant messages on the internet, instant world wide news coverage, world wide telephone services and all the other global advances we have now. The Americans did not know what Europe was like or about the cruelty of the Nazis or the suffering of the people who were oppressed by the Nazis. There were some Americans and Canadians who did report what was going on but the Americans failed to realize the gravity of the murdering and cruel acts of the Nazi Germans.
Even the soldiers from the US who went to the European Theater of Operations truly did not realize why they had to defeat the Nazis. Some of the soldiers and Marines who found the concentration camps admitted they never really understood why they had to fight until they saw the thousands of dead Jews in the camps and the ones who were barely clinging to life.
The isolationism was a fruit of the misunderstandings of 1919 armistice, the Treaty of Versailles and the tragedies of the Great War. Once the Americans had their own people and place attacked they realized they could no longer avoid being involved in the war.
Many Americans thought Europe was a mess and they didn't want to enter another bloody war like World War I.
It wanted to stay isolated. It did not want to get involved into a 'European' affair. The German sinking of the Lusitania was a reason the U.S. entered Worl War I and the Japanese bombing of Pearl Harbor, Hawaii was the reason the U.S. entered World War II.
They got involed in the war because the Japanese bombed pearl harbour.
The Japanese attack of Pearl harbor
The U.S. refused to be drawn into international cooperative organizations during and after the war.
A reason that is NOT for the Civil War is to get more land.
The US didnt want war
The US was attacked.
The Islamic terious want to go to war with the us because the us is full of greedy corporate jews that control the world trade centres and started 9/11, they are also the reason behing OWS.
In World War I, USA helped Britain in the war however they joined in the war 1917 and didn't involve a lot that was part of the reason why they didn't want to punish Germany after World War I. They helped by supplying troops and armies.
1 reason was us want latest jet technology of germeny( nazi) 2 reason was us want defeat germany because he knows that germany work on atom bomb and if he make it he destroy all us after uk. 3 reason was that us want a new market for his weapons
The US did enter World War 1, though not till 1917.
World Peace.
It wanted to stay isolated. It did not want to get involved into a 'European' affair. The German sinking of the Lusitania was a reason the U.S. entered Worl War I and the Japanese bombing of Pearl Harbor, Hawaii was the reason the U.S. entered World War II.
You don't even want to know the real reason.
the us decided to enter world war because they want the resources of france, and they want to keep on ruling france.
the sinking of the Lusitania.
us did not want to be part of it
