What are the factors required to pull off a successful soft Coup?

How many of those factors have already been met?

What factor or factors are still outstanding?

How much prevention and investigation has been applied to preventing this?

Surely the most important area that needs investigating is how deep the corruptive force has penetrated the military .

Remember 911 the protective force of the military was diverted north of NY.
With Benghazi and the troops being ordered to stand down.

You can have Patriot troops , but if orders are counter to maximum protection , gaps appear.
