A British father took his 9-year-old son to the Dover coast, from which they looked at the busy marine traffics between England and the continent. "If a really thick fog descended on the England Channel," the father told his son, "the continent would be COMPLETELY isolated!"
Many American fathers will say the same to their young sons with regard to the Eurasian Continent.

'But would that be better for the US? Of course not. In some respects, America is already an island on the shores of Eurasia. It cannot hope to isolate itself from the affairs of its larger neighbour, and its economy, at least, would find it impossible to delink from a war-ridden Eurasia.'
