"Recent American research has shown that as early as 1880, the British Empire was producing an economic return lower than investment in Britain itself, while to preserve it the British taxpayer was paying two and a half times more for defence than the citizens of other developed countries. If its military, administrative, and financial costs were added together, the empire was a bad economic bargain. The Soviet Union is now learning from its own experience in Eastern Europe and Central Asia that Lenin's theory of imperialism is contrary to the facts; the cost of holding colonies abroad is greater than the value of the markets or raw materials they may provide."
