U.S. national security underpins the system in which Americans live. National security is essential to an environment and geographical space in which people can reside without fear. It consists, first, of physical security on both the international and domestic sides. This includes protection from threats external to the country and safety in the homeland. These generally are accomplished through hard power and homeland security efforts. Second, it consists of economic security—the opportunity and means for people to provide for their own well being under an economic system that is vibrant, growing, and accessible. Third, U.S. national security involves outreach through soft power in an attempt to win the "hearts and minds" of people across the globe. Soft power complements hard power, and, in cases, may substitute for it. Also, the myriad links between governments, businesses, and people across national borders means that American security increasingly depends on countries and activities in far flung places on the globe. Traditionally, the economy entered into the national security debate through four issues: the defense industrial base, base closures and program cuts, international economic sanctions, and export controls. These issues still garner much of the attention from the vantage point of the military. From the point of view of the nation as a whole, however, economic security takes on a broader meaning. This report examines the role of the economy in national security from both macroeconomic and microeconomic points of view. The macroeconomic issues center on the budget and deficit reduction. The microeconomic issues focus on providing for the general well-being of the people and in supporting other components of national security. This report also examines the major sources of long-term economic growth and progress and policies that affect them. It further addresses the coordination of policies among nations, particularly the G-20, and foreign policies that affect human rights, the development of democracy, and U.S. economic assistance. This broad review of economics and national security illustrates how disparate parts of the U.S. economy affect the security of the nation and that security is something achieved not only by military means but by the whole of the American economy and how it performs. In national security, the economy is both an enabler and a constraint. The economic issues related to national security are both broad and complex. In order to keep this report to a manageable length, this study takes the President's 2010 National Security Strategy as a beginning construct and largely limits the analysis to the issues raised there. The purpose of this report is to provide an overview of the economic contributors to national security as well as to furnish links to further resources. Issues, such as reducing the federal budget deficit, immigration, international trade, or innovation, are related to national security in ways that are too numerous and complex to address fully here. Further information can be found in the CRS reports cited or can be obtained by contacting the CRS analysts indicated. In the United States, the renewed public debate over national security appears to be generated primarily by three global changes. The first is the nature of the external threat to physical security—the rise of terrorism and militant Islam. The second is the aftermath of the global financial crisis, particularly the large federal budget deficit and slow rate of recovery. The third is the growing presence of emerging nations, such as China, India, and Brazil, and the shift of economic power toward them. These changes have created gaps and trade-offs that arguably are undermining the sense of security of Americans. Some may say, "What good is protection from a future threat, when I am unemployed because my job just went to China?" Others may say, "What good is a high salary, if I am dead in a terrorist attack? This debate over national security reaches deep into the fiber of American society. It is not merely political theater, and it is receiving a fillip by the weakened U.S. economy. A vibrant, growing, and dominant economy can hide a multitude of problems. Even though wealth and economic means cannot guarantee U.S. security, it can buy a comfortable sort of insecurity. The economic issue of the day now centers on what measures to take to return the economy to its long-term growth path and reduce the gap between the potential and actual levels of U.S. gross domestic product. If the economy were to grow faster, many of the constraints on the federal budget would be eased. There are two major schools of thought on this matter. The Keynesian approach to growth is to continue government deficit spending through the recession and initial recovery phase in order to offset lower consumption by households and reduced levels of investment by businesses. When the economy recovers, the deficit can be reduced. The supply side approach is to cut the federal budget deficit now because deficits may discourage investment by causing uncertainty about future policy changes that will be needed to restore fiscal balance. The supply side approach also attempts to keep taxes on entrepreneurs low in order to induce them to invest more in productive capacity and create more jobs. Each approach recognizes that the long-term security of the nation depends greatly on having a vibrant and growing economy. Congress plays a major role in each element of national security. Whether it be policies dealing with the military, economy, budget, education, economic growth, technology, international relations, or opening markets abroad, Congressional action is essential. Not only does Congress provide funding for these elements of national security, but it provides oversight, defines the scope of U.S. action, and provides a crucible in which U.S. policies are debated and often determined. Congress allocates the resources to respond to national security threats, and in so doing it plays a part in determining the relative strength of hard and soft power options and the roles individual agencies will play. The Goldwater-Nichols Department of Defense Reorganization Act of 1986 ( P.L. 99-433 ) required that the President provide a National Security Strategy (NSS) for Congress. This document presents the major national security concerns of the country and how the existing administration plans to deal with them. The George W. Bush Administration's issued its final NSS in March 2006, and in May 2010, the Obama Administration released its first NSS. The 2010 NSS noted numerous world conditions, laid out a national security strategy, and set some goals, many of them economic. It began with three observations: the world is now in a moment of transition, of sweeping change; globalization has both opened opportunities and intensified the dangers Americans face from terrorism, the spread of deadly technologies, economic upheaval, and changing climate; and even as the war in Iraq ends and the focus of military action has turned to Afghanistan, a superior military is necessary as the United States faces multiple threats from nations, nonstate actors, and failed states. The NSS then laid out some goals, both military and economic, along with policies deemed necessary to ensure a safe and secure United States. Those related to the economy were: in order to build an America that is stronger, more secure, and able to overcome challenges while appealing to aspirations of people around the world, the United States must foster economic growth, reduce the federal budget deficit, educate our people, develop clean energy alternatives, pursue science and innovation, and build capabilities and alliances to pursue interests shared with other countries and peoples; the United States seeks an international order and cooperation with other nations that will counter violent extremism and insurgency, stop the spread of nuclear weapons, combat climate change, sustain global growth, and help countries feed themselves; and the United States will continue to advocate for and advance human rights, economic development, and democracy as a bulwark against aggression and injustice. The challenge of the twenty-first century is to adapt U.S. policy to account for how the world has changed. These changes can be highlighted by reviewing some traditional perceptions that helped shape U.S. security policy. During the latter half of the twentieth century, five large ideas seemed to have permeated politics in the Western world writ large: peaceful settlement of issues was better than going to war (no more world wars, although regional conflicts persisted); other countries would tolerate U.S. hegemony in exchange for keeping the peace; the United States and Europe could determine policy on most major international issues; the United States could assist countries to democratize because democracies were more likely than dictatorships to have shared values and to keep the peace; and Western culture was appealing and more universal than any other. These fundamental ideas played a large role in shaping and maintaining U.S. national security first in a bipolar world shrouded in the Cold War and then in a more multi-polar system in which countries, such as China, have gained relative economic power and have brought a different set of interests and values to the table. While each of the above ideas has carried over to a certain extent into the twenty-first century, each also has eroded considerably. Similarly, in the economic and financial realm, four large ideas or priorities helped shape both U.S. domestic and international economic policy: market capitalism was superior to socialism (high standards of living, vibrant entrepreneurs, and innovation were nourished best by free markets); security considerations trumped economics (e.g., wars had to be won even at high economic cost; U.S. retaliation against allies in trade disputes [such as those with Japan and South Korea] had to be tempered by its potential impact on alliance relationships); economic growth and employment were best fostered by monetary and fiscal policy rather than by industrial policies that "picked winners and losers"; and imbalances in trade and capital flows were largely self correcting (foreign exchange rates determined by capital markets and appropriate government fiscal and monetary policy would bring balance into international accounts). These economic and financial precepts still hold sway, but they are being challenged by an evolving and demanding security and economic environment.
