The timing of power

Why do "rising powers" cause wars in international relations? This dissertation argues that as a state grows in power, there are (1) more issue areas over which it can come into conflict with other states, and (2) on those issues where there is conflict of interest, those conflicts are more difficult to resolve peacefully. Stated more simply: "rising powers" create situations in which there is more to fight about and less willingness to resolve these issues without war. Since 1800 the sole path to rising power has been industrialization, which generates new needs for resources and foreign markets. When the international system's distribution of benefits (DOB) is flexible, these new needs are unlikely to create conflicts of interest. When the DOB is sticky, or when the rising state has substantial pre-existing national interests, conflicts of interest become more likely. Where a conflict of interest exists, situations of rising power make it more difficult to achieve a peaceful resolution through bargaining. This is because rising states find it more difficult both to make threats and to send assurances, the two signals necessary for successful bargaining. The dissertation's empirical section uses a comparative case study method. In the 19 th century, the United States did not fight a war with Britain because the distribution of benefits was fluid and, therefore, no major conflict of interest emerged. However, because the United States was unable to send effective threats and assurances to Spain, the two states fought a war in 1898. The sections on Japan argue that it was the new interests generated by Japan's rise which created conflict of interest with the U.S. The fact that leaders on both sides saw the other state as rising rendered both threats and assurances ineffective and led to the breakdown of bargaining. The expansion of Chinese interests today has not led to war because the contemporary distribution of benefits is quite fluid. However, the same difficulties signaling threats and assurances are evident in contemporary decisions in Chinese foreign policy. This difficulty remains a major potential pathway to conflict during China's rise.
