The primary means for the expansion of state power and the elimination of rival exploitation centers is war and military domination. Interstate competition implies a tendency toward war and imperialism. As centers of exploitation, their interests are by nature antagonistic. Moreover, with each of them--internally--in command of the instrument of taxation and absolute counterfeiting powers [i.e., central banking and fractional reserve new money creation], it is possible for the ruling classes to let others pay for their wars.
