The balance of power, depended on its effectiveness upon clearly defined, centrally controlled, independent entities, whether empires or nation states, which recognize each others sovereignty and territory
Answer:
A century.
Explanation:
I say a century because we can automatically knock out forever and a millennia because resources can not last forever and 1000 years (a millennia) just isn't reasonable.
10 years is just too short, even with the current consumption per year

Good luck!
