The alternative is conflict and the search for allies. At present the U.S. and its German allies, on whom Washington bases its European policy, are in the ascendant. But experience suggests that no ascendancy can last forever, and that the time for preparation to adjust to change is before changes begin, not after. Unless this is done, all present and future manipulation of frontiers, nations and histories will be useless and counterproductive. But meanwhile the juggernaut rolls on.
Empires differ in their objectives.
The Greek city-states founded colonies abroad of their own citizens, to expand their own being. The British tried to expand Britain by creating colonies in North America and the Antipodes, but then let the colonies slip out of their grasp. One can understand the principle of U.S. involvement in Cuba, Guatemala, or Haiti, even if one does not necessarily approve of particular policies. The U.S. has traditionally worked with some ugly despotisms, and is still doing so, viz. Saudi Arabia, Kuwait, or Pakistan.
