Americans have never felt at ease with empire, and with good reason. Running an empire often demands that we betray our republican ideals, at least for periods of time. It can also be costly in gold and in blood.

Politicians in both parties assured us that we could off-load our responsibilities onto a “global” market mechanism, overseen by a new institution created in 1995 called the World Trade Organization (WTO).
