"It was only after European firearms reached a certain stage of effectiveness in the nineteenth century that it became possible for whites to colonize and dominate the whole world. Similarly, the invention of a massive array of new instruments of destruction in the metropoles was both a psychological and a practical disincentive to colonized peoples seeking to regain power and independence. It will readily be recalled that a basic prop to colonialism in Africa and elsewhere was the “gunboat policy,” which was resorted to every time that the local police and armed forces seemed incapable of maintaining the metropolitan law and the colonial order of affairs. From the viewpoint of the colonized, the strengthening of the military apparatus of the European powers through colonial exploitation was doubly detrimental. Not only did it increase the overall technological gap between metropole and colony, but it immeasurably widened the gap in the most sensitive area, which had to do with concepts such as power and independence."
