"But this is not a detail that is easily retconned. Snake will return to the United States and retake command of FOXHOUND in order to play the double role he undertakes in Metal Gear 1 and fight his son in order to pursue the Outer Heaven Uprising."

Yeah, it's not easily able to be retconned, but then again, so was the total disarmament procedures of MG2 and OILIX, not to mention fighting Big Boss to end his nightmares and succeeding (which are very important details to MG2, heck, most of them were pretty much the reason why Snake was even involved in the events of the game), yet guess what? They actually did retcon it quite a bit.
