Every generation gets the Constitution that it deserves. As the central preoccupations of an era make their way into the legal system, the Supreme Court eventually weighs in, and nine lawyers in robes become oracles of our national identity. The 1930s had the Great Depression and the Supreme Court's "switch in time" from mandating a laissez-faire economy to allowing New Deal regulation. The 1950s had the rise of the civil rights movement and Brown v. Board of Education. The 1970s had the struggle for personal autonomy and Roe v. Wade. Over the last two centuries, the court's decisions, ranging from the dreadful to the inspiring, have always reflected and shaped who "we the people" think we are.
During the boom years of the 1990s, globalization emerged as the most significant development in our national life. With Nafta and the Internet and big-box stores selling cheap goods from China, the line between national and international began to blur. In the seven years since 9/11, the question of how we relate to the world beyond our borders-and how we should-has become inescapable. The Supreme Court, as ever, is beginning to offer its own answers. As the United States tries to balance the benefits of multilateral alliances with the demands of unilateral self-protection, the court has started to address the legal counterparts of such existential matters. It is becoming increasingly clear that the defining constitutional problem for the present generation will be the nature of the relationship of the United States to what is somewhat optimistically called the international order.
This problem has many dimensions. It includes mundane practical questions, like what force the United States should give to the law of the sea. It includes more symbolic questions, like whether high-ranking American officials can be held accountable for crimes against international law. And it includes questions of momentous consequence, like whether international law should be treated as law in the United States; what rights, if any, noncitizens have to come before American courts or tribunals; whether the protections of the Geneva Conventions apply to people that the U.S. government accuses of being terrorists; and whether the U.S. Supreme Court should consider the decisions of foreign or international tribunals when it interprets the Constitution.
