Information power: Strategy, geopolitics, and the fifth dimension

In response to some of the current literature, this analysis argues that th e information age will not invalidate the importance of physical geography in geopolitics and strategy. Although recognising that the infosphere repre sents a fifth dimension of strategy, the author contends that the strategic limitations of information power signify that physical expressions of mili tary power will continue to dominate the practice of strategy. However, the infosphere is perhaps attaining greater significance. Consequently, this e ssay explores the nature of the fifth dimension, and outlines 'control of t he infosphere' as a useful strategic concept for the twenty-first century.
