War Plan Red


Staff member
Joint Army and Navy Basic War Plan Red, also known as the Atlantic Strategic War Plan, was a plan for the United States to make war with the British Empire (the "Red" forces). It was developed by the United States Army following the 1927 Geneva Naval Conference; and approved in May 1930 by the Secretary of War and the Secretary of Navy, updated in 1934–35. In 1939 it was decided that further planning was no longer applicable but that the plan be retained. [1] War Plan Red was declassified in 1974.
The war was intended to be a continental war, waged primarily on North American territory between the United States and the British Empire. The assumption was that Canada would represent the primary theater of operations.

Pretty interesting. Wonder how that would have turned out.

It was kind of interesting looking at some of the other rainbow war plans.

War Plan White Dealt with a domestic uprising in the US, and later evolved to Operation Garden Plot, the general US military plan for civil disturbances and peaceful protests. Parts of War Plan White were used to deal with the Bonus Expeditionary Force in 1932. Communist insurgents were considered the most likely threat by the authors of War Plan White.

In addition there were combinations such as Red-Orange, which was necessitated by the Anglo-Japanese military alliance which expired in 1924.

Was there ever a war plan for Ireland?
Keep the beer and whiskey flowing so they do not take over the world. ;) As I tell people the good Lord created whiskey so the Irish would not rule the earth.

But I'm sure they have/had an old war plan somewhere for it.


Any Nation could take over Ireland.
Just promise to lower the price of alcohol.
