A Well Regulated Militia

Does the statement "A Well-Regulated Militia" really change the meaning of the Second Amendment to a state or collective right as opposed to an individual right as some argue? Or does the militia stem from a collection of individuals utilizing their individual rights to keep and bear arms? Is the Militia just the National Guard or the entire armed populace of a community, state and nation? Was the Second Amendment a right dreamed up by gun loving founding fathers or a right that has existed with humanity since their very existence? These questions will be answered in this book, A Well Regulated Militia.
