Allowed B&F to purchase arms from USA provided they paid in cash immediately and have their own transport

Allowed USA to remain neutral as they did not have to deliver the goods themselves and provide B&F with the weapons they urgently needed

Britain was fighting alone and was approaching bankruptcy and could not afford to pay for the military supplies it needed to fight Germany

Roosevelt called for the US congress to approve of the Lend-Lease Act.

Gave the President power to send military and non-military goods to any country he deemed important to USA's interests and national security

Payment can be deferred and they do not have to be responsible for the transportation of the goods

Roosevelt held secret talks with Churchill to discuss how USA could best help Britain

USA exchanged 50 Naval Destroyers for 8 British Naval Bases

When German submarines emerged a threat, USA ordered the US navy to provide escort service to all allied ships

USA was the biggest industrial power at that time

Converted all its industries to military production quickly

USA sent not only military and non-military goods, but also military personnel, soldiers and strategists, to Britain

Allied manpower was strengthened significantly with the arrival of US soldiers

Successful bomb attacks on German Cities and military sites prevented important resources from reaching Germany

Campaign to open up mainland Europe with the goal of not only liberating Nazi-occupied Western Europe, unseat Hitler and end WW2 in Europe

Although Allied suffered many casualties, they managed to gain a foothold in mainland Europe

Conclusion: USA initially pursued a policy of isolationism to avoid being drawn into the war. However, in the end, staying out of the war was impossible. The USA became directly involved in the war and played a significant role in defeating Germany

His refusal to listen to trained and more experienced military generals cause him to make many wrong military decisions

Gave the British RAF time to strengthen themselves and prevent Germany from defeating Britain

Allowed the Soviet Union to eventually beat the German Army

There was no cooperation but competition for resource to strengthen themselves in the three Military Sectors (Army, Navy, Luftwaffe)

German Labor Force consisted of slave laborers from Nazi-Occupied countries who were often worked to death

Allies, on the other hand, made sure that their women worked in Military Industries to keep production going.

Allies, on the other hand, focused on fewer but a more decisive range of weaponry, which ensured the availability of spare parts.

Allies, on the other hand, were more focused on the suitability of the weapons they produced.

The Germans failed to ensured the continuous supply of oil, which is essential to their mechanized army

They did not have their own oil fields and it depended on the oil it gained from the occupied countries and the synthetic fuel it produced from its local industries.

This brought the mighty German War Machine to a virtual halt.

Hitler committed a huge mistake by Involving Germany in wars on both the West and the East

This allowed USA to send war equipment to the Soviet Union to fight Germany

Hitler wrongly assumed that an isolated Britain would not be a threat on his Western Front and the USA would only commit their troops to fight the Japanese in the Asia Pacific region.

The two-front war was divided and overstretched the German Army, causing its defeat. The German Army did not have sufficient resources to fight both fronts simultaneously.

Hitler was a fanatic nationalist and militarist who wanted Germany to conquer and rule in Europe. His refusal to listen to his generals and his idealistic military strategies eventually led to the defeat of Germany.

To Stalin's disbelief, Hitler invaded the Soviet Union in June 1941, ignoring the Nazi-Soviet Non-aggression Pact. The Soviet Union then allied itself with Britain to defeat Germany

The Soviet Union was not prepared for German Invasion and suffered heavy casualties. Initially, it seemed as if the German would have an easy victory, just as they did in Western Europe.

However, the Soviet Union benefitted from tactical errors made by the Germans, as well as the cold Russian winters that the German troops were unprepared for. They used that time to regain their strength by reorganizing their military structure and rebuilding their military production.

The Soviets also benefitted from the military equipment which Britain and the USA has sent to fight the Germans

The Germans failed to defeat the Soviet Union because they were trained only to fight short, decisive battles and not long extended wars.

When countries in Western Europe fell to Germany, Britain was all alone. However, Britain was determined not to negotiate with Hitler and was determined to defeat him.

British Prime Minister Winston Churchill played a key role in motivating the British by instilling the confidence in them that Hitler could be defeated.

Hitler has assumed that Britain would surrender once France was defeated and thus was not prepared for was against Britain.

German attempts to defeat Britain through aerial warfare failed as the strategy to bomb cities and not the military installations and bases led to Britain gaining valuable time to regroup the RAF and defeat the Luftwaffe

This led to Britain being preserved and become a launchpad for D-Day.

This prevented essential resources from reaching Germany

Gave the Allies greater opportunities and success at bombing German cities and Axis military sites

Many of those in Nazi-occupied territories were determined to liberate their countries from German occupation and that led to the growth of resistance fighters.

The most significant resistance groups were based in France, Yugoslavia, Poland and the Soviet Union. The Allies encouraged and supported the resistance movements as they were aware that the success of their military operations depended on the information that the resistance groups provided them with. They also provided protection to Allied operatives working in Nazi-occupied territories.

The communists often led the most successful resistance movements. This resulted in many people joining the communist-led movements. They were not attracted by the communist ideology but rather the patriotism for their homeland.

The resistance movement in Europe during World War 2 played an important role in defeating Nazi Germany's military might.

US aircraft took off from British air bases to carry out regular bombing of German Cities, vital industries, rail links and synthetic oil plants

By 1944, as many as 1000 bombers were attacking Germany daily, escorted by around 800 fighter planes

The German Waffles tried to shoot them down, but lost aircraft in the process. German air bases were also bombed.

This resulted in the waffles not being able to recover.

American-occupied Greenland and Iceland gave Britain vital bases over the Mid-Atlantic

This made sure that Allied Ships could cross the Mid-Atlantic.
