The Protectionist Fallacy Makes Expansionist Wars More Attractive

Many serious people across the American political spectrum either affirmatively support or do not oppose the peaceful acquisition of Greenland. No serious political observer endorses the incandescently stupid notion that the United States should incorporate Greenland by force — to say nothing of the other obnoxiously frivolous threats Donald Trump issued from the podium on Tuesday against American allies like Canada and Denmark.

 

We should be clear: Trump’s refusal to rule out the use of the U.S. military to create the Greater American Co-Prosperity Sphere is not a clever negotiating tactic. The prospect is not credible, and those who retail notions like that detract from their own credibility. That may be little sacrifice for influencers on social media, where credibility is already in short supply. But provocation for provocation’s sake is entertainment, and we too often confuse the business of American public life with amusing spectacle.

 

But there is something to be said about a particular disposition that regards territorial expansionism as a necessary tool of statecraft. It is the sort of outlook that was common to policymakers in the pre-War world — an environment typified by inviolable spheres of influence in which international free trade agreements were far rarer. If you are inclined to see resource acquisition as a zero-sum competition for finite commodities — indeed, if you view trade as a form of war by other means, as Moscow did in the years preceding its adventurism in Ukraine — you’re more likely to see expansionist wars of conquest as vital national projects.

 

The research on the subject is hardly ambiguous. Nations “with high levels of trade with their allies are less likely to be involved in wars with any other countries (including allies and non-allies), and that an increase in trade between two countries correlates with a lower chance that they will go to war with each other,” the abstract of a 2015 study published in Proceedings of the National Academy of Sciences read. While that’s not always the case, the exceptions prove the rule. “Free trade, and not just trade, promotes peace by removing an important foundation of domestic privilege—protective barriers to international commerce—that enhances the domestic power of societal groups likely to support war,” University of Texas, Austin, professor Patrick McDonald determined in 2004 debunking the socialist myth that World War I was a byproduct of “commercial liberalism.”

 

Put simply: “Open trade makes war a less appealing option for governments by raising its costs.” We can debate whether the U.S. would derive more strategic benefits from the formal acquisition of Greenland than it draws from the military basing rights Washington already enjoys in that territory. Certainly, the notion that the development of Greenland’s rare-earth minerals — a daunting logistical feat — cannot be acquired through mutually beneficial commercial means is a baseless assertion (particularly since it will be commercial interests that will develop the technology necessary to do so). There is no question that the resources sacrificed in a hostile engagement with the interests who would oppose American expansionism exceed the possible rewards. That inescapable conclusion should compel those who value their authority to admit what they know to be true: This is a silly thing to talk about.

 

Trump is not “thinking big.” Rather, the president-elect and those who have entertained his thought bubble as though it was a serious proposition have demonstrated their adherence to a dangerous fallacy. It’s no coincidence that the renewed popularity of protectionist thinking has made the prospect of war more thinkable.
