United States military deployments

The military of the United States is deployed in most countries around the world, with more than 160,000 of its active-duty personnel stationed outside the United States and its territories. This list consists of deployments excepting active combat deployments, including troops in Iraq, Syria, Yemen, and Somalia.
Outside of active combat, US personnel are typically deployed as part of several peacekeeping and classified missions, military attachés, or are part of embassy and consulate security.

Rationale

Statements by U.S. military and government

A longstanding justification for maintaining military installations worldwide for the United States is that a military presence abroad by the U.S. promotes and strengthens democracy.
When asked about the reason behind U.S. military presence in Germany, former Supreme Allied Commander Europe Alexander Haig said that "the presence of U.S. troops keeps European markets open to us. If those troops weren't there, those markets would probably be more difficult to access." Adding, "On occasion, even with our presence, we have confronted protectionism in a number of industries, such as automotive and aerospace. In addition to economic benefits derived from our presence in Europe, there is perhaps an even more important diplomatic and political benefit."

Statements by others

According to Hermann and Kegley, military interventions have boosted democracy in other nations. The majority of academics, however, concur with professor of international politics Abraham Lowenthal that American efforts to spread democracy have been "negligible, often counterproductive, and only occasionally positive."
JoAnn Chirico believes that, as of 2014, the U.S. military presence and installations are often considered responsible for suppressing democracy in countries such as Cameroon, Chad, Ethiopia, Jordan, Kuwait, Niger, Oman, Qatar, Saudi Arabia, and United Arab Emirates.
In her 1979 essay, "Dictatorships and Double Standards", Jeane Kirkpatrick argued that although the United States should encourage democracy, it should be understood that premature reforms may cause a backlash that could give the Communists an opportunity to take over. For this reason, she considered it legitimate to support non-communist dictatorships, adding that a successful and sustainable democratic process is likely to be a long-term process in many cases in the Third World. The essence of the so-called Kirkpatrick Doctrine is the use of selective methods to advance democracy in order to contain the wave of communism.
