What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

497 - Nazis Up the Mississippi, And Other Axis Invasion Scenarios

January 18, 2011, 5:57 PM

It's early 1942, and the future looks bright for Nazi Germany. What parts of mainland Europe the Wehrmacht hasn't conquered outright, are held in thrall to Germany in uneven alliances or uneasy neutrality. Out east, German armies are gobbling up big chunks of Soviet Russia in a seemingly unstoppable race towards Leningrad, Moscow and the oilfields of the Caucasus. 

So confident are the Nazis of the war's outcome that they've declared war on the US on 11 December of the previous year, four days after their Japanese allies obliterated America's Pacific Fleet at Pearl Harbor. 

The Japanese Empire itself is also near the acme of its power, making giant inroads into British, Dutch and American holdings in the Far East, adding to the Empire's conquests in China.

It's unclear - in fact, highly unlikely - that either Germany or Japan had any concrete plans beyond continental hegemony. For one thing, no contemporary maps illustrating global ambitions of the German-Japanese Axis survive (1). But if there ever was a time the Axis might have thought it had a shot at conquering the entire world, this was it.

That terrifying momentum was felt most keenly in the United States, which until recently was half convinced it could sit out this world war on the sidelines. Now a reluctant belligerent, America saw itself caught between two hostile, agressive powers, one over each coastal horizon. 

In those early days after its involuntary entry into the war, panic must have been a palpable feature of the nation's mood. While it mobilised for the best, America feared for the worst. In its March 2, 1942 issue, Life magazine distilled that national anxiety into six maps, each portraying a different scenario for Axis invasion.

Plan One detailed a combined Japanese-German invasion, each hostile power invading via the most opportune shore. Plans Two and Three showed how a solo Japanese invasion might play out, while Plans Four through Six demonstrated various options for a solely German operation. 

Below is each scenario, with the original legend in italics.

Plan One

Plan One (…) attack on U.S. base at Dutch Harbor with all Jap aircraft carriers and the Fleet reinforced by German battleships, presumably giving naval superiority. Japs capture air bases, much as they advanced through the East Indies. Then their land-based planes help the carrier planes to protect the next sea advance down the West Coast. An American fleet flings itself into the fight. U.S. fifth column, heretofore held in reserve, blows up the country. The Japs take the West Coast aviation industry, shipyards and oil wells. Then Germans stab at East Coast.


Plan Two

Plan Two calls for a frontal attack on the West Coast via Pearl Harbor. This is the hard way. Japs supported by carriers first land on the outer Hawaiian Islands, set up air bases and close in on Oahu. More difficult is the big water jump, protected only by carrier-borne planes, to San Francisco.


Plan Three 

Plan Three calls for a southern Pacific crossing by Japan. Again the Jap Fleet, reinforced by the Germans, presumably has naval superiority over the U.S. Fleet. Probably first gun would be surprise bombing of Panama Canal, instantly followed by landings in Ecuador.


Plan Four

Plan Four is the much-discussed invasion by way of Gibraltar-Dakar-Natal-Trinidad, which President Roosevelt’s Good Neighbour policy has tried to defend against. It is based on combining the Jap, German, Italian and Vichy navies, freed by the capture of Gibraltar and Suez. They must fight the Allied fleets somewhere. Invasion pours up the Mississippi Valley.


Plan Five

Plan Five is hard way to cross the Atlantic. Combined Axis navies reduce Atlantic islands, then take big water jumps from Azores to Bermuda to Norfolk. Their biggest headache is reported U.S. superiority in carriers. Twenty-five Nazi ships could transport four divisions.


Plan Six 

Plan Six is classic invasion down St. Lawrence and Hudson valleys. Germans could readily bomb Chicago, Detroit, Akron and rampage through Midwest. Big catch is getting past British Fleet. On all maps, black arrow alone means a feint; when combined with gray band, it means full invasion.


Maybe it's the benefit of hindsight, but each of these scenarios now looks highly improbable, and more reflective of the acute necessity, for the benefit of the war effort, to transform American angst into American anger. The Japanese taking the Galapagos Archipelago, establishing air bases in Ecuador? Really? A Nazi armada taking New Orleans and trundling up north through the Mississippi valley? Really? A fifth column, supposedly composed of German-Americans and/or Japanese-Americans, aiding the enemy? Really?
