I believe two periods have already ended...
1.renaissance and scientific method
2.cold war boom, i.e. nation-state superpower

I believe we are already in a third era...TIA total information, total control, both overt and covert. Nation states are now in name only and are tools for only the most elite families. Power is now with international banking cartel families, which directs force of control.

What is the end-game? Russia, China, United States, England... Israel, France, Japan, Germany...Denmark, Norway, Sweden, Switzerland... the major players.
