Now, more than ever, the United States might be tempted to pull back from the world. That would be a mistake, since an engaged grand strategy has served the country exceptionally well for the past six decades -- helping prevent the outbreak of conflict in the world’s most important regions, keeping the global economy humming, and facilitating international cooperation.
Despite a decade of costly and indecisive warfare and mounting fiscal pressures, the long-standing consensus among American policymakers about U.S. grand strategy has remained remarkably intact. As the presidential campaign made clear, Republicans and Democrats may quibble over foreign policy at the margins, but they agree on the big picture: that the United States should dominate the world militarily, economically, and politically, as it has since the final years of the Cold War, a strategy of liberal hegemony. The country, they hold, needs to preserve its massive lead in the global balance of power, consolidate its economic preeminence, enlarge the community of market democracies, and maintain its outsized influence in the international institutions it helped create.
To this end, the U.S. government has expanded its sprawling Cold War-era network of security commitments and military bases. It has reinforced its existing alliances, adding new members to NATO and enhancing its security agreement with Japan. In the Persian Gulf, it has sought to protect the flow of oil with a full panoply of air, sea, and land forces, a goal that consumes at least 15 percent of the U.S. defense budget. Washington has put China on a watch list, ringing it in with a network of alliances, less formal relationships, and military bases.
The United States' activism has entailed a long list of ambitious foreign policy projects. Washington has tried to rescue failing states, intervening militarily in Somalia, Haiti, Bosnia, Kosovo, and Libya, variously attempting to defend human rights, suppress undesirable nationalist movements, and install democratic regimes. It has also tried to contain so-called rogue states that oppose the United States, such as Iran, Iraq under Saddam Hussein, North Korea, and, to a lesser degree, Syria. After 9/11, the struggle against al Qaeda and its allies dominated the agenda, but the George W. Bush administration defined this enterprise broadly and led the country into the painful wars in Afghanistan and Iraq. Although the United States has long sought to discourage the spread of nuclear weapons, the prospect of nuclear-armed terrorists has added urgency to this objective, leading to constant tension with Iran and North Korea...
