He exaggerates the differences between Obama and Romney on foreign policy, but Henry Nau makes a comment that deserves a little more discussion:
The foreign policies of Obama and Romney, or what is now the loyal opposition, could not be wider apart. Obama’s foreign policy is inordinately piecemeal, even picayune. It lacks a vision that draws connections between specific issues, such as terrorism, and the broader American interest to protect and promote freedom [bold mine-DL]. The loyal opposition, by contrast, connects the dots between terrorism and authoritarian challenges to American and global freedom.
There is a real difference here in that the “vision” that Nau describes is a mish-mash of Bush-era ideas that didn’t make sense ten years ago and still don’t today. Obama didn’t ever fully subscribe to these views, and he made a point of moving away from the folly of the “freedom agenda” at the beginning of his first term. Is there a connection between issues of terrorism and “protecting and promoting freedom”? No, there isn’t. What connections are there between terrorism and “authoritarian challenges to American and global freedom”? There might be some extremely tenuous connection somewhere, but the truth is that these issues (assuming we can treat the entire phenomenon of terrorism as a single “issue”) are not closely connected. Are there authoritarian challenges to American freedom? If so, they can only come from Americans, since there is no foreign power today capable of restricting that freedom.
Linking these things together was a clumsy, arbitrary move by the Bush administration that was eager to push its “freedom agenda” in tandem with waging the “war on terror” as if one had much to do with the other. One of the major flaws of the foreign policy of the Bush administration and the views of his supporters was the tendency to conflate and link things that had no connection. Advocates for invading Iraq did this most famously when they promoted spurious claims of links between Iraq and Al Qaeda. The habit of linking unrelated things was a common error often informed by the bad habit of imagining that “values” and interests could be advanced together without trade-offs. Insofar as Romney represented a return to these false assumptions, Americans and other nations around the world were fortunate that he lost the election. The “vision” that Nau attributes to Romney is a fantasy that distorts understanding of the issues that it forces together.

The vision thing only makes “sense” with hindsight.
Historians typically only list programs that succeeded. Seldom do they mention ones that failed. Even history’s progressions and regressions are only discerned by subjectively connecting the dots afterward and then without adherence to strict discipline.
Cause and effect can be objectively determined with a degree of accuracy in the hard sciences and in the applied sciences. Determing cause and effect in the humanities, history or political science, however, might be safe to do in a freshman term paper, but they remain etheral and basing public policy on grand ideas is irresponsible and bordering upon the insane.
Daniel, you are right to declare the emporer still has no clothes. Trying to philosophically cobble together the fetid detritus left over of all the failures of the last ten years into some grand design only produces some real visions of horror. True conservatives seldom embrace the “vision thing.” Conservative “intellectuals” dislike our not doing so, but following the tried and true really is the only sane path.
True conservatives realize that man has always proposed and that God has always disposed and that anyone wailing “But I meant well!” to absolve himself of policy failures is really just a leftist at heart.
