Check out the movie: Seven Days in May.
I am one of the doubters of the Business Plot.
One of the things we’ve seen in the Middle East is that the military is not some monolithic machine, but a bunch of human beings. In Egypt, they had too much contact with the civilian population to want to protect the government. In Libya, the military has disappeared. In the East, solders and officers have thrown their support to the rebels. In Tripoli, Qadaffi has to rely on mercenaries to keep the government in power. Many officers and government officials have resigned and moved over to the rebel side.
Coups happen when there is no long democratic tradition, so solders aren’t worried about overthrowing a legitimate government. Many times, the military has its own power base such as the ability to get cash without having to depend upon government budgets. This could be the illegal drug trade, or the military owning profit making businesses.
The problem with the Business Plot is somehow they’d all march on Washington and seize the controls of the nation. Yet, Washington is a minor city. Besides, you have fifty state governments to contend with.
There have been comparisons with Mussolini’s march or Rome, but the March on Rome wasn’t just a “march on Rome”. By the time the march took place, many Northern Italian cities were already in the hands of the Fascists who overthrew the legitimate governments of those cities. Fascists were also strong in the military which could not be trusted to protect the government in Rome.
In Southern Italy, Fascists and Communists militias were battling in the streets. By the time the Fascists reached Rome, Italy was on the brink of a civil war between Fascists and Communists.
It would have taken more than a veterans march on Washington to do what Butler claimed would have happened.
