[Late 1930s] The American position regarding
Europe was isolationist (isolating one 's
country from the affairs of another's).
President Franklin D. Roosevelt was
determined to keep out of war. In 1937, this
sentiment was further seen to be clear
through the passing of the Neutrality Act
However, Roosevelt warned the public that USA would
certainly be threatened by Germany, Japan, and Italy
eventually. This was especially so after the countries
signed the Anti-Comintern Pact in 1936-1937. He warned
to aggressor nations, that countries that advocate war
should be treated as threats to the public health, and
should be excluded or isolated. Although wanting to
prevent war, he feared that the USA would be involved in
a war militarily eventually, and thus prepared for such a
possibility
Original indirect involvement
'Cash and
Carry'
and
'Lend-Lease
Act'
In 1939, during a revision of the Neutrality Act of
1937, Roosevelt persuaded the American Congress to
allow Britain and France to buy Arms from the USA
on a 'cash and carry' (Britain and France may buy
goods from USA if they paid in full and transported
on their own basis. This allowed him to provide aid to
the two countries while remaining neutral
In 1941, Winston called for help due to
Britain's exhausted resources. Roosevelt
persuaded for Congress to pass the
Lend-Lease Act that gave him authority to
supply weapons, food, and equipment to
any country whose defense he thought
was vital to the national security of USA
'Arsenal of democracy'
Roosevelt's argument
for the USA was that
the USA should be the
'arsenal of
democracy' - which
means that USA ought
to actively support
democratic nations
(i.e. Britain and
France) in fighting the
Axis Power
After the fall of France in
June 1940, Britain was the only
major Allied country in
Europe not fallen to Germany.
Roosevelt thus persuaded
Congress to give 'all aid short
of war' to increase USA's
level of aid to Britain
Other forms of aid
The USA provided Britain and her allies with
military supplies, and rapid rearmament
Roosevelt also imposed economic sanctions
on the Axis Power to deprive them of
resources needed for their war effort
When Japan wanted to
expand its empire in the Far
East, Roosevelt restricted
supplies of important
materials (i.e Japan) from
1940 onwards
On 7 December 1941, the Japanese attacked the
American Pacific Fleet at Pearl Harbor. On 8
December, Congress declared war on Japan. Due
to the Tripartite Pact (between Italy, Germany,
and Japan), Hitler also declared war on the USA
Contribution of vast resources and manpower
The USA was the world's largest
producer of goods at the time. It could
convert its factories for military
production at a faster rate than the
Axis Powers. When USA formally
entered the war, they sent large
numbers of American military
personnel. It boosted the military force
and the industrial capacity of the Allied
Powers
Collaboration with Allies on military strategies
The American participation in the
Allied military strategies was
invaluable, helping the Allies achieve
control of the air and the sea
The control of the air and sea helped
greatly in Allied tactical successes
against Germany, such as the 'Operation
Overlord', and the D-Day Landings
Germany's weaknesses and miscalculations
Ineffective command structure
The German state and military command
structure suffered from confusing system
of overlapping authority
Apart from Hitler, no one else had the
power to make decisions. Hitler often went
against the advice of his experienced
generals - which proved to be mistakes
such as those during the Battle of Britain
and the invasion of the Soviet Union
Inappropriate use of resources and military funds
For instance, Hitler demanded for the most updated weaponry but some
of these types were mass-produced before being tested on the battlefield
There was a lack of adequate personnel for armament
production as women stayed at home instead of helping with
the war efforts (due to Hitler's discriminating policies against
women) and the factories were staffed by starving slave laborers
To make matters worse, the involvement of USSR and USA
greatly boosted the Allies' resources and military funds
Heavy reliance on petroleum
Although Germany had very little natural petroleum reserves of its own, but
it was the chief resource that powered its war machine. Germany relied on
synthetic oil by liquefying coal, a resource that Germany had in abundance
From 1943 onwards, German synthetic oil plants and oilfields were subjected to
heavy Allied aerial bombing, led by the USA. Germany's oilfields in Nazi-occupied
countries like Austria and Romania, were put out by the Soviet Red Army and
the American Air Force. Thus, their war machine almost came to a halt
War on two fronts
Hitler's greatest mistake was deciding to
conduct a war on two fronts. While still on
war with Britain in the Western Front, he
chose to invade the Soviet Union, opening up
the Eastern Front. Then, while he appeared
to be gaining the upper hand against the
USSR, he decides to declare war on USA.
Hitler assumed that the USA would be primarily fighting
Japan in the Pacific. However, Roosevelt concentrated his
troops and efforts in North Africa and Europe. Hitler is
now fighting a war on two fronts at the same time
Allied resistance
Reorganization of the Soviet Union
The USSR helped to defeat about 80% of the
German armed forces on the Eastern Front
On 22 June 1941, Germany broke the Nazi-Soviet
Non-Aggression Pact and invaded the USSR. In response,
the USSR formed a military alliance with Britain on 12
July 1941, and entered war on the side of Britain
Although facing challenges and threat from the Germans
initially, the USSR eventually gained the upper hand
German tactical errors, strong resistance from Soviet
troops, and the bitter Russian winters of 1941 and 1942
gave the USSR time to reorganize its army and rebuild
its economy and military production. It then gained a
greater advantage over Germany, especially after the
American Land-Lease aid was extended to them
British resistance to German invasion
Hitler never planed for a war with the British.
When France fell in June 1940, he hoped that
the British would discuss peace terms together.
However, Churchill made it clear that he
planned to fight the Germans to the finish
Hitler realized that it would
be hard to invade Britain
with his usual Blitzkrieg,
which depanded on the
deployment of great
numbers of land troops,
which would not work well
on the island nations of
Britain. Thus, Germany
would need to achieve its air
and sea supremacy
In 1940, Germany
attacked Britain in the
Battle of Britain. With
strained sources, Britain
was further weakened by
Germany. Although the
German tactics were
successful, tactical
changes by Hitler
undermined German
military effectiveness and
gave the British time to
recover. The constant
German bombings
strengthened the morale
and resolve of the British
instead of weakening it
Resistance movements
Resistance movements in
Nazi-occupied European countries
worked dangerously, but provided
vital information and behind-the-lines
support to the Allies
Until 1941, resistance was
limited, as the Nazis'
sudden invasion left most
people too traumatized to
contemplate resistance.
This changed after Hitler
invaded the USSR. The
communists (used to
working underground)
became actively involved in
resisting the Nazis. Many
civilians who opposed the
Nazis joined the
communist resistance as
they saw it as a successful
resistance movement
