Forum:When did the patriots take over America in the metal gear series

a question that been bugging me for some time now is when did the patriots cement there rule over America? from what iv been able to gather through research they patriots themselves where formed in the 1970's using the philosophers legacy and from what i know there control over the U.S government was complete at about the Early 2000s when George Sears was appointed as the 43rd American President.what i'm trying to figure out at what point they went from subtly manipulating agencies in the government(the pentagon,CIA, DOD,DARPA,etc,etc) to complete ilimantiesq control of the entire nation.can anyone help me pin down a specific date or at lest narrow it down to a decade and/or relevant presidency
