States have two kinds of power: latent power and military power.

The ideal situation for any state is to experience sharp economic growth while its rivals' economies grow slowly or hardly at all.

When World War II started on September 1, 1939, the German army contained 3.74 million soldiers and 103 divisions.

The German air offensives against British cities in World Wars I and II not only failed to coerce the United Kingdom to surrender, but Germany also lost both wars.

States care about relative wealth, because economic might is the foundation of military might.

The most dangerous states in the international system are continental powers with large armies.

Simply put, the most powerful state is the one that prevails in a dispute.
