That is the plan the Germans had for WW2, but USA knew this would be the case so they gave aid to those countrys, Cash and Carry being one, and then To Protection Cash and Carry. Out of the 100 million tonnes of supplys, 1 million was been lost. The more the Aid the Better, America was in no dirrect involvment with War and could stay Nutrual.
In 1939 out of 100 People in USA. 91 said they wanted to have nothing to do with war in Europe.
In 1940, 85 said the same.
In 1941, before PH, 80 said the same.
Figures could be one or 2 out.
So now if Germany didn't invade USSR, and finished of England, if Japan didn't Attack Pearl Harbour, this plan could have worked. Using the real time info we had on USA's war production up untill PH
I think if Germany invaded England and won, taken Ireland also, then there would no where to land in europe. Iceland also. Covered by both captured fleets and Air Support. Europe was in no danger from any country from invasion. And stops supplys to USSR. Full sub fleet, No support available to USSR. Both seas in control of enemy. Finland axis with Germany, because of USSR Invasion.
The Japanese have started there run in Asia, then If a push from both sides of Russia, Japan from the East and the Finish attacking into Leningrad and cut off the northern front with German Soldiers, Then pushed down to Moscow, and to the Oil fields. metting up with German troops all across the 3 Fronts , The USSR would have been busy with enemy on all borders.
Middle east oil fields would be next, and with unlimited supplys of Oil from USSR and Arab oil, Africa be the next target, when in complete domination of Europe, Middle East, Asia and Africa, Germany and Japan would control 2/3 of all the land mass in the world, and 6/8 of the population of thw world. With unlimited supplys of Labour, Oil, Wood, Coal, Gold, metal, iron, and just about everything you can think off.
By this stage the Americans were not involved in the war, Pearl harbour didn't happen yet, so the Americans were not full strength with the Army, and they were not in full gear for war. But with the continuous expansion of Hitler, they would have start increasing the army and navy. America knows that an attack will come, as American borders are surrounded by the enemy.
As with America in full swing and moving up gears, all industry for the axis powers are in War drive, over 6/8 of world population enslaved. Axis decide that South America is next, and Japan will move on to Canada through Alaska, with Canada been taken, and most of the Nazi groups in S America would welcome Germany like Austria. In S America, alot of the wealthy were from German decent.
An aggrement held by all of the countrys in South, Central, and North Americas to Stop Hitler steping foot on any part of any America.
Argentina gives German support, a landing spot with out land casulity, and industry not been distroyed, start the buildup of Armys of Argentina and Germany.
Germany Delclars war on America. The USA in Full Swing now. Some of the countrys in S America decide to axis with Germany fearing what will happen to them after the war, some fight and are dystroyed. Germany is a well trained Army, with constant supplys and good equipment as unlimited supplys gives you the best of everything.
South America is Taken.
Canada are putting up on massive fight, with USA building up forces and sending some to help Canada and South America, homeGuard is created.
With combined forces take Pacific from USA. Atlantic is covered by French, German, British ships from different countys covering USA from Greenland, Iceland, Ireland, to Fortress Europe to Mexico. Japan on the other side.
So Hitler with his new Navy, Aircraft carriers, with help from Japan's navy designers, unlimited resources, This with Combined forces with Japan and all axis Countrys would hold USA on 2 fronts with no help from anyone would eventaly have to fall.
