The trouble with talking about seapower is that it is so difficult to say just what it is. The gentleman who first used the term as an abstraction to describe a complex of forces of great historical influence never defined it. This was perhaps wisdom on his part. If you have a good phrase, with a manifest but undefined relation to reality, it is probably best to leave it a little vague and so acquire the support of many who might take exception to a too precise formulation.
