## Defense and Foreign Policy Studies The scholars in the Cato Institute’s Defense and Foreign Policy Studies Department believe that the United States should engage the world through diplomacy, mutually beneficial trade, and extensive cultural exchange. --- ### Overview The Cato Institute’s foreign policy scholars believe that the United States should engage the world through diplomacy, mutually beneficial trade, and extensive cultural exchange. The use of military force may be warranted when America’s vital national security interests are threatened, but only as a last resort. Cato scholars argue that America should model the principles of liberty, democracy, and human rights. We therefore advocate transitioning from our current grand strategy of primacy to one based on restraint. America’s global influence is greatest when spread by peaceful means.

Nearly two decades later, and with the counterterrorism mission complete, it is time to end America’s military mission in Afghanistan. A negotiated end to the war and the removal of all U.S. forces from the country in a deliberate but expeditious fashion is in America’s national interest.

Yet, at a time when Washington seeks an agreement with Pyongyang about its nuclear weapons program, America has withdrawn from two historic deals (the INF and the JCPOA) and is unlikely to extend New START. Instead of undermining and degrading the existing arms control infrastructure, America should strengthen and modernize it to address new technologies and changing international dynamics.

U.S. arms sales policy should prioritize transparency, data collection, and risk mitigation.

Unfortunately, that strategy has not delivered the intended results. It’s time to turn the page in the War on Terror and adopt policies that better reflect the serious but limited threat that terrorism poses to the United States.

Many aspects of the U.S. government’s response to COVID-19 merit scrutiny. There will be a thorough review of policies and procedures that might have slowed the spread of the virus, but the primary focus should be on stopping the spread of the disease and caring for those who have contracted it. Policymakers must also consider how this crisis will shape Americans’ collective understanding about present and future threats and how to address them effectively.

This is the result of the growth in U.S. domestic production as well as the changing global oil market. Militarily, no country or nonstate actor is able to cut off U.S. consumers’ access to oil. Thus, while energy security remains important, it is far less problematic today than in previous decades and does not require substantial military action abroad.

A lack of trust between the nations makes negotiating compromises exceedingly difficult. But instead of a policy of “maximum pressure,” U.S. policymakers should prioritize sustained engagement to develop trust and mutual respect and to lay the foundation upon which a durable relationship can be constructed and conflict can be avoided.

However, China and Russia believe the steady expansion of the size and sophistication of America’s missile defense systems undermines their respective nuclear deterrents, prompting both to make countermoves. The action-reaction spiral threatens nuclear stability at a time of increasing tension among great powers.

The country is blessed with its relative geographic isolation, prodigious nuclear deterrent capabilities, diverse and resilient economy, and abundance of natural resources. However, many policymakers see things differently. Intelligence assessments and government reports often exaggerate foreign-based national security threats. Such threat inflation leads to excessive government spending and a misallocation of resources. It often results in policies that erode fundamental civil liberties and can be detrimental to U.S. national security.

After years of war in the Middle East, polling in 2013 and 2014 recorded historically low support for global engagement, and the election of Donald Trump in 2016 led many in Washington to worry about whether the American public was turning inward. It turns out that American internationalism is not dead, but simply evolving.

A more effective policy would acknowledge the unpleasant realities of today’s U.S.-Russian relationship while focusing on deterrence and reengagement on critical issues.

The administration should have held deliberate and calculated discussions with Turkey, the Kurds, Damascus, and perhaps even Moscow to mitigate the negative consequences of U.S. withdrawal prior to the president’s announcement.

Unfortunately, the historical record demonstrates that sanctions are rarely successful in achieving their objectives, especially on issues of high salience, such as questions of war and peace. By overusing sanctions, policymakers risk degrading America’s global economic power and harming its national security.
