U.S. overseas troops have been stationed in American allies to secure the local balance of power favoring allies in a military confrontation. Such an expectation would deter challenges from potential adversaries. People believe that the maintenance of U.S. stationed troops is indispensable for securing American allies. However, the U.S. has been reducing the size of U.S. overseas troops since the end of World War II. The reduction of U.S. overseas troops does not always lead to deterrence failure. Why is that?
The answer is that the U.S. can send a credible signal of its resolve to protect allies through its budgetary decisions. Given the size of the reduction in the federal budget due to economic difficulties, the U.S. can convey its resolve to protect a specific ally by maintaining or marginally reducing the budget for stationed troops in this ally.

Our studies examined how political and economic events shape the approval ratings in Japan. We addressed both foreign and domestic events. Events have a variety of effects that are constant over different periods of time. Not only events but also news reports shape the Japanese public opinion. News reports on North Korea and South Korea shape the Japanese public’s affinities to those countries, while economic news reports change the Japanese cabinet approval ratings. Finally, the probability of cabinet approval converges at the individual level because the longer tenure of the cabinet leads to the spread of information.
