Which city-state does the following quote most closely relate to?

"The fundamental motif through all the centuries has been the principle that force and power are the determing factors. All development is struggle. Only force rules. Force is the first law... Only through struggle have states and the world become great. If one should ask whether this struggle is gruesome, then the only answer could be -- for the weak, yes, for humanity as a whole, no. Instead of everlasting struglle, the world considered in the light of their ultimate consequences, are the causes of the downfall of all humanity."
