When the Berlin Wall fell, Warsaw Pact dissolved, and Soviet Union split apart, U.S. foreign policy became obsolete almost overnight. For a brief moment advocates of a quasi-imperial foreign policy seemed worried.
For instance, NATO advocates were reduced to talking about having the anti-Soviet military compact promote student exchanges and battle drug smuggling. But advocates of preserving every commitment, alliance, and deployment quickly recovered their confidence, insisting that the status quo now was more important than ever.



Since then NATO has expanded, Washington has “rebalanced” toward Asia. The U.S. has fought a succession of wars. Despite public disquiet over multiple foreign disasters, the political elite remains remarkably united in backing America’s expanding international military role.
Leading Republicans simply refused to acknowledge George W. Bush’s mistakes, instead shamelessly blaming Barack Obama for the Iraq debacle and all that followed. Democrats who opposed Bush’s Iraq invasion said little as the current president escalated old wars and initiated new conflicts and drone campaigns. GOP presidential candidates competed over how much murder and mayhem they would wreak. Hillary Clinton pushed for U.S. military intervention in the Balkans as First Lady, voted for the Iraq war as Senator, and orchestrated the Libya campaign as Secretary of State.
