When it comes to the international system, realists believe that changing distributions of power are dangerous. The territorial boundaries, spheres of influence, and international regimes of the old order may no longer be stable. A rising power may use its newfound military capability to change existing territorial boundaries or even to completely conquer and annex all of the territory of a neighboring state. Extant spheres of influence within which a dominant power is able to influence or dictate the important foreign policy choices of subordinate states, including their security alliances and trade policies, may crumble, if they are challenged by a rising power that can make credible threats with regard to military action and trade sanctions, or offer promises of greater security or prosperity. International regimes, whose rules, norms, principles, and decision-making procedures have been taken for granted or at least not actively challenged, may not be sustainable if a rising power refuses to adhere to them or offers some alternative principles and rules that might be more attractive for weaker states.
The classic example of the dangers presented by power transitions is the rise of Germany in Europe in the late nineteenth and first half of the twentieth centuries. The following table shows the percentage of world capabilities for major countries from 1870 to 2007. These scores are based on the composite index of national capabilities (CINC), which is derived from six indicators (energy consumption, iron and steel production, military expenditure, military personnel, total population, and urban population). The table clearly shows the rise of German power from 1870 to 1939. Germany’s share of world power increased from 11 percent in 1870 when its still trailed Britain and France, to 16 percent on the eve of the first world war when it was the most powerful state in Europe but still trailed the United States, to 18 percent in 1939 when it was tied with the United States at the top.
