Hand in hand with nationalist economic isolationism, militarism struggles to maintain the sovereign state against the forward march of internationalism.

It is against this concept of the sovereign state, a state isolated by protectionism and militarism, that internationalism must now engage in decisive battle.

Earlier ages fortified themselves behind the sovereign state, behind protectionism and militarism.

No state is free from militarism, which is inherent in the very concept of the sovereign state. There are merely differences of degree in the militarism of states.

Militarism is basically a way of thinking, a certain interpretation of the function of the state; this manner of thinking is, moreover, revealed by its outer forms: by armaments and state organization.

Like all social theories, internationalism must seek its basis in the economic and technical fields; here are to be found the most profound and the most decisive factors in the development of society.
