Through the long sweep of American history, there have been many occasions when public opinion, or at least an important part of it, got ahead of politicians in demanding war. Many of the Indian wars were caused less by Indian aggression than by movements of frontier populations willing to provoke and fight wars with Indian tribes that were nominally under Washington’s protection—and contrary both to the policy and the wishes of the national government. The War of 1812 came about largely because of a popular movement in the South and Midwest. Abraham Lincoln barely succeeded in preventing a war with Britain over the Trent Affair during the Civil War; public opinion made it difficult for him to find an acceptable, face-saving solution to the problem. More recently, John Kennedy, Lyndon Johnson and Richard Nixon were all haunted by fears that a pullout from the Vietnam War would trigger a popular backlash.

It is often remarked that the American people are more religious than their allies in Western Europe. But it is equally true that they are more military-minded. Currently, the American people support without complaint what is easily the highest military budget in the world. In 1998 the United States spent as much on defense as its NATO allies, South Korea, Japan, the Persian Gulf states, Russia and China combined. In response to widespread public concern about a decline in military preparedness, the Clinton administration and the Republican Congress are planning substantial increases in military spending in the years to come.

Americans do not merely pay for these forces, they use them. Since the end of the Vietnam War, taken by some as opening a new era of reluctance in the exercise of American power, the United States has deployed combat forces in, or used deadly force over, Cambodia, Iran, Grenada, Panama, Lebanon, Libya, Saudi Arabia, Kuwait, Iraq, Turkey, Somalia, Haiti, Bosnia, Sudan, Afghanistan, the South China Sea, Liberia, Macedonia, Albania and Yugoslavia. This is a record that no other country comes close to matching.

Why is it that U.S. public opinion is often so quick—though sometimes so slow—to support armed intervention abroad? What are the provocations that energize public opinion (at least some of it) for war—and how, if at all, is this "war lobby" related to the other elements of that opinion? The key to this warlike disposition, and to other important features of American foreign policy, is to be found in what I shall call its Jacksonian tradition, in honor of the sixth president of the United States.
