2+2=5 says it all
With that Gestaltian magic in mind, Yglesias says:
Progressives see a positive-sum world and believe in advancing American interests by means of including allowing others to advance their own interests. Progressives recognize the Hobbesian aspects of the international system that make positive-sum interactions difficult to obtain, but we see this as a challenge that can be overcome and seek means of overcoming it. Conservatives, meanwhile, are perpetually tempting fate—by sending the message to the world that America cares most about preserving its power relative to others, we indicate that the only way for others to advance their interests is by undermining our position. On human rights, conservatives have (recently) embraced the rhetoric, but the deeper structure of their worldview makes it impossible to incorporate genuine concern for the well-being of foreigners inevitably rendering professions of humanitarian concern hollow and opportunistic.
This translates to:
Conservatives value a world in which each seeks their local way as best suited to them and recognize that this best promotes global development by means of the invisible hand. Conservatives recognize the Hobbesian aspects of the world that makes harmonious independent interactions difficult to obtain, but see this as a challenge that can be overcome and seek means of overcoming it. Progressives, meanwhile, perpetually undermine their own aspirations — in seeking to coerce inclusion and legislate uniformity in the name of material equality, they undermine the very legitimacy of their thinking and the very grounds from which development flows. Whether speaking of individual autonomy or local diversity the deeper structure of their worldview makes it impossible to affirm the inherent good of either, and inevitably renders celebrations of such empty and duplicitous.
