"Moreover, if the territorial state is to continue as the last word in the development of society, then war is inevitable"

In this quote, Christian Lous Lange is suggesting that if the concept of a territorial state stays the dominant type of social organization, then war is bound to occur. This is because the idea of a territorial state is based upon the notion of a defined geographical location with a centralized government, which frequently leads to competition and conflict with other states. Lange is suggesting that as long as this system continues, there will constantly be a battle for power and resources, eventually resulting in war. He is highlighting the fundamental flaws and repercussions of the territorial state model and promoting for alternative forms of societal development to prevent future disputes.
