A Pentagon metastasized almost beyond recognition

Who, today, even remembers the debate at the end of the Cold War about what role U.S. military power should play in a "unipolar" world? Was U.S. supremacy so well established, pundits were then asking, that Washington could rely on softer economic and cultural power, with military power no more than a backup (and a domestic "peace dividend" thrown into the bargain)? Or was the U.S. to strap on the six-guns of a global sheriff and police the world as the fountainhead of "humanitarian interventions"? Or was it the moment to boldly declare ourselves the world's sole superpower and wield a high-tech military comparable to none, actively discouraging any other power or power bloc from even considering future rivalry?
