Romney's misguided peace through strength
My general rule is to discount most of what is said during campaign season since: 1. politicians will say anything to get elected; 2. events can (and should) meaningfully change positions once a candidate becomes an office-holder.
That said, since Mitt Romney's foreign policy speech is being hailed by many neoconservatives as a welcome return to American strength, it's worth pointing out that it's built on a non-sequitor:
'Third, the United States will apply the full spectrum of hard and soft power to influence events before they erupt into conflict. Resort to force is always the least desirable and costliest option. We must therefore employ all the tools of statecraft to shape the outcome of threatening situations before they demand military action. The United States should always retain military supremacy to deter would-be aggressors and to defend our allies and ourselves. If America is the undisputed leader of the world, it reduces our need to police a more chaotic world. {Emphasis mine}'
While I certainly wouldn't argue with the need to retain military supremacy against would-be adversaries, the highlighted section isn't true. If America acts in the manner described by Romney - which is a role it has followed arguably since 1990 - it means a constant resort to policing the world by force. Since the later half of the Cold War and its aftermath, when American power was at its apex, when America was "indisputably" the leader of the world, the pace of American military interventions and conflicts soared.
The "peace through strength" philosophy would be appealing if it were actually true, but in the current application there's very little that's peaceful about it. It would be one thing if the U.S. retained a preponderance of military power but only used it when absolutely necessary. That would truly be "peace through strength." But the variety being peddled by Mr. Romney and his cheerleaders is the perpetuation of war and interventionism in the name of maintaining hegemony over the world. The "peace" part is not much in evidence.
