What was the MAIN reason of WWII!?
443967
As you know, WW1 started with the assassination of an Austrian leader. At the end of WW1, Germany was still in a depressed state (like economic depression), and the time was ripe for new radical leadership with the ousting of the old. This new radical leadership, along with the newly invented propaganda machine of television, and Germany's economic state of despair, were the reasons for WW2. Hitler believed expansion of his "kingdom" (third Reich) was essential for Germany's economic prosperity. And at the time, gold was a limited supply, same as today, except that all money was backed by gold. Today, money is not backed by gold. And a limited supply of money made war an economical advantage, they war, they win, they take your gold. Today war is an economical burdon, it is not for gold, but for power.

During WWII, there was a real need for soldiers to get supplies that were essential for them to fight: food, gasoline, rubber and the like.  The US's ability to get some of these was further hampered by disruptions to shipping due to the war.  Therefore, rationing was set up to ensure that there would be no worries about leaving the soldiers in poor supply, as well as making sure the general public was adequately provisioned. \nPeople got stamp books for certain goods, with varying levels depending on the scarcity of the goods.  People also had a point system which they could use to figure out what they could get. \nNot shockingly, there was a black market that sprung up of people selling extra goods for a profit.  The government tried to convince people to honor the ration system and avoid the black market.\nThere was also a very strong propaganda effort to help ensure that people sacrificed and did not waste and helped the war effort. People were also encouraged to use substitutes, grow their own food, and join carpooling clubs.

it was mainly two things.  Frist was the left over effects that WW1 had incuding the treaty of versaillies that made alot of germans with a bad taste in their mouth.  The second is Nationalism. This is an plotical idea that is sesnse of belong to a coummity that shared historaicl, politcal, ethical, Geographal, and religious tranditions.  In the most extreme way (like Nazi Germany, Facist Italy, and Imperal Japan) it is used ina way that people in a country feel like their country and race is the best and other people from other countries and races are below them. this is a good starting point. I hope this help and good luck.

World War II was a BIG factor in the USA becoming a power house. Also the 40's produced one of the biggest baby booms in US history for the 50's.

WWII was thought of Germany's "revenge" or rebirth after the shame it was brought due to the Treaty of Versailles. Germany was made to pay the countries it affected after the war and limit the number of military troops. Germany was not present during the discussion of the treaty and it felt wronged. Hitler used this is a spin to bring the Germans to rally behind him. WWI is actually considered the "unfinished war" and WWII was just a continuation.

World War 2, was won by the allies, Due to their ,Unity, Discipline, &Superior Weapons, Training, STRATEGY,& Courage.\nAlso due to the ULTIMATE ISOLATION, of GERMANY, & THE fact that the GERMANS, tried to fight on SO MANY FRONTS, SIMULTANEOUSLY.

Because he needed to be. The Americans never ever were in that awful situation, in which were the English at the beginning of the Second World War. The English were alone against the Germans who conquered all Europe, and had better and more armament than the English who developed the radar and the air-force in the last moment. Mr.Winston Churchill became the leader whom we remember until today, because of the war, maybe in other circumstances he couldn't prove what is capable. The great man was in the right time in the right place.

1) the US wanted to get the Japanese back for the bombing of Pearl Harbor\n\n2) the US wanted to intimidate the Soviet Union \n(because there were tensions between the US and the former Soviet Union and the US wanted to show the Soviet Union that it had a new, deadly weapon which the Soviet Union didn't have)\n\n3) Truman justified the dropping of the bomb by stating Japan would not surrender without an invasion that'd cause enormous loss of both American and Japanese lives. At least, with Hiroshima and Nagasaki...no American lives were lost (*rolls eyes*)\n\n\nThe bombing of Hiroshima came first (August 6, 1945), the US dropped the bomb in hopes Japan surrenders.\nSince Japan didn't surrender, 3 days later (August 9, 1945) the US dropped another atomic bomb on Nagasaki. \nJapan got the point, surrendered, and World War 2 was over.

Well, winning World War II set the United States up to be a world power.  It also helped ushered in a great deal of long-overdue reforms in Europe, and today a European Federal Constitution is now a very real possibility.  Further still,  had Hitler succeeded, he would have undoubetly gone on to destroy the United States indescriminatently.  He would not have spared a single American, even those who resembled his ideal race, because they had grown up in a culture that was, in his eyes, dirty and corrupt (not to mention we were his sworn enemy).  This is one of the many instances in which money plays no role, so the 2.6 trillion figure you site is meaningless.  And even though the use of atomic weapons is still controversial, that alone does not aide your case 'was stopping _Hitler_ worth it.  I'm frankly shocked and appauled that someone could use their freedom of speech, something that wouldn't be enjoyed in a Hilter-ized America, in such a blatantly ridiculous manner.

To sacrifice 100,000+ Japanese lives for possibly millions of Japanese, European and American lives.  The war would have continued if it were not for "the bomb" - and once on mainland Japan, it would have been disastrous.  The Japanese actually did not surrender until after we bombed another city, Nagasaki, several days later.  This is a testament to their will and determination at that time.\n\nThe other important thing to remember is that Germany was also developing a nuclear device and was ahead of us with delivery systems (rockets, missiles, etc.), so it was imperative that we not only develop the bomb(s), but demonstrate that we had them and their effectiveness, as horrible as that sounds.\n\nNuclear weapsons are a terrible thing, cost countries billions of dollars to develop, and if used again, will most likely damage the planet irreparably.

It's basicly the Nazi invasion of Poland after the Allies gave Hitler an ultimatum. Here are some more causes ... \nhttp://www.rpfuller.com/gcse/history/6.html

Basically World World II was like a continuation of World World I. Essentially this is what happened. World War I starts (aka - The Great War pre WWII) and afterwards its like everyone took a break. I'm not joking either. It was like a pause for 20 years. In the early 1930's, Japan invaded China. China actually had the most amount of casualties, not Russia or Eastern Europe. \n\nMost countries blamed Germany and so Germany had many sanction and restrictions put on the country. Hitler played off of these emotions and blamed the Jewish population for all of Germany's problems. At this time, Hitler was also quickly moving up in the ranks and finally became Dictator. \n\nHitler then started annexing countries in the mid to left 1930's and every country began to appease him. After he took over Poland and much of France, it was too late. The non-aggression pact between Germany and Russia made Hitler essentially invulnerable because from Eastern Europe was essentially all his to take over minus Russia. (Hitler would later reneg on the non-agreesion pact)\n\nThe United States needed an excuse to get into WWII and they finally got one on June 6, 1941 - Pearl Harbor. \n\nAbout 6 million jews were killed and 6 million gypsies, homosexuals, etc were killed. \n\nIn China, about 20-25 million were killed.

Because in Hitler's mind, the Jews were Untermenschen, i.e., 'underlings' or 'subhumans', who were seen as both biologically inferior and a potential challenge to the superiority of the 'Aryans'.\nHitler's book Mein Kampf makes clear Hitler's racist worldview, dividing up humans based on ancestry. Hitler stated that German "Aryans" were at the top of the hierarchy, and assigned the bottom of the order to Jews and Gypsies. Hitler went on to say that dominated peoples benefit by learning from the superior Aryans. Hitler further claimed that the Jews were conspiring to keep this "master race" from rightfully ruling the world, by diluting its racial and cultural purity and by convincing the Aryans to believe in equality rather than superiority and inferiority. He described the struggle for world domination as an ongoing racial, cultural, and political battle between Aryans and Jews.

Germany's desire for revenge... or for a more complete explanation: http://en.wikipedia.org/wiki/WWII

the roots of the nazi party would be a reason. I've never heard of this though.

The answer to this is complex and depends on whose history you read. However, the European side of WWII was caused solely by Adolf Hitler's quest for power.  He used tactics such as the Dolchstoss Legend, which stemmed from the "stab in the back" sentiments of the Treaty of Versailles, to gain power.  These tactics gained him wide support from Germans who were still bitter from their loss of WWI.  It also rallied anti-semitism because this legend, in part, blammed the Jews for the loss.  Initially Great Britain and France followed a policy of appeasement towards Hitler, allowing him to take over former German lands such as Czechoslovokia.  However, Hitler kept wanting more. WWII started after Hitler invaded Poland in September 1939.  Great Britain and France, allies of Poland, declared war two days later. \n\nOf course, if you look at WWII from the point of view of Asia, the war started much earlier.  According to China, the war started when Japan invaded them and the infamous Rape of Nanking occurred.  \n\nThe US became involved initially with the Cash and Carry policy developed in 1939.  The US, still struggling with the economic depression, used this to remain neutral but to fuel the need for industrial jobs.  After a while, though, Great Britain and France could no longer afford to pay the US for goods and the US enacted the Lend-Lease program in 1941.  This program allowed for much the same, but the Allies were not paying for the goods immediately.  Therefore, it could be argued that since the US only provided goods to Allied forces, we were involved in the war since 1939. \n\nHowever, most pinpoint US involvement as occuring shortly after  December 7, 1941 (the attack on Pearl Harbor by the Japanese).    Nazi Germany declared war on the United States on December 11, with Hitler wanting to declare war on US before we could declare war on anyone. The United States was fuming at the Japanese, but the president decided to focus more on the European front first, making that top priority.
