Guests: Rosella Cappella Zielinski (Boston University), Paul Poast (University of Chicago)

Episode Overview

This episode explores the central themes of "Wheat at War," a new scholarly book by Rosella Cappella Zielinski and Paul Poast. The conversation delves into the overlooked but crucial role of logistics and, specifically, wheat supply during World War I, highlighting how Allied economic cooperation—not tactics alone—shaped the course of the war. The discussion brings out the origins, significance, and legacy of the Wheat Executive, an inter-Allied body for coordinating wheat procurement and shipping, and what this historical case reveals about international cooperation, economic warfare, and lasting institutional innovation.

Key Discussion Points and Insights

1. Motivation and Background of the Book

[02:26]

• The authors share a mutual fascination for the "unappreciated" logistical backbone of warfare: “What we really got to appreciate about each other was the appreciation of the, quote, unquote, unappreciated. And that unappreciated is exactly what you mentioned, this back end of war, all of the coordination that comes prior to that tip of spear..." — Rosella Capella Zielinski
• Their academic backgrounds—Cappella Zelinsky on war finance, Poast on alliances—inspired an integrated approach to how wars are paid for, supplied, and logistically supported.

2. Discovery of the Wheat Story and Jean Monnet's Role

[04:22]

• The project sprang from archival research into World War I finance, where Jean Monnet, later a father of the European Union, played a key role in Allied food coordination:
  • “Jean Monet...this nugget of international cooperation comes from wheat during World War I and coordination. And we were like, wait, what wheat? We do not know this story.” — Rosella Capella Zielinski
  • The authors uncovered that Monnet’s innovations in wheat coordination later inspired European integration post-WWII.

3. The Wheat Crisis and Allied Response

[08:54]

• Participants outline the acute wheat shortages faced by Britain and France:

  • Britain imported 4 out of every 5 slices of bread; trench warfare destroyed local crops, and Russian wheat was cut off by the Central Powers.
  • This led to domestic shortages and political pressure, captured in Allied propaganda:
    • “Food will win the war. Wheat is needed by allies. Waste nothing.” — Rosella Capella Zielinski

• The crisis was compounded by German unrestricted submarine warfare and a North American wheat crop disease called stem rust, which drastically reduced available supply (see [12:22], [15:37]):

  • “At the same time that you had German unrestricted submarine warfare...you have less wheat even available to send to Europe because of this epidemic.” — Paul Poast

4. Creation and Function of the Wheat Executive

[19:34–25:00]

• The Wheat Executive (est. November 1916) represented the apex of Allied economic cooperation:

  • It consolidated authority for purchasing and shipping wheat across Allied nations, making efficiency-driven decisions regardless of national interest.

  • Members were tasked to think not as national representatives but as “Allied officials.”

  • The Wheat Executive also managed all associated shipping decisions through its Freight Committee, preventing inefficiencies like empty ships passing one another.

  • It expanded to manage other grains and coordinate supply for neutral and smaller countries.

    “You are not to think of your stuff as a British official or a French official or an Italian official. You were to think of yourself as an Allied official, and you were to make decisions based on what's best for the Allies.” — Paul Poast [19:34]

  • Effectiveness: It stabilized market prices and became a model for other commodity executives (sugar, rubber).

  • The Wheat Executive's institutional innovation led directly to the creation of the Allied Maritime Transport Council, which coordinated shipping at an even larger scale—a system complete with its own flag, highlighting its quasi-sovereign function.

5. Role of the United States and the Limits of Cooperation

[28:44–33:59]

• When the U.S. joined the war, it initially approached resource allocation with a “mine, mine, mine” mentality, showing reluctance to cede sovereignty.

  • U.S. entry forced both adaptation and limitation of Allied cooperation due to American insistence on autonomy and control over its own supplies, revealing both potential and boundaries of multilateral economic governance.

• Postwar, the U.S. further withdrew, preferring a return to open markets and declining ongoing economic coordination, even as it advocated for the (ultimately failed) League of Nations.

  • “You really do see this play out on the economic side. You see how the US is like, hey, you all cooperate, but we're not going to really give up too much sovereignty on this…” — Paul Poast [33:59]
  • “It's ironic that the USA scuttles this, but then is pushing for the League of Nations...” — Joby Turner [33:13]

6. Legacies and Historical Significance

[38:03–40:11]

• The Wheat Executive left a clear institutional legacy:
  • Its model of problem-solving and international authority informed later efforts at global governance, including WWII institutions (Bretton Woods, United Nations).
  • After the war, European powers wanted to retain economic cooperation; the U.S. did not, leading to the failure of projects like the Supreme Economic Council.
  • These failures and later reflections directly shaped how Allied powers approached multilateral coordination in WWII (immediately calling on Jean Monnet, for example).
    • “[WWII leaders] immediately call him [Jean Monnet]…let's start with the Wheat Executive. We don't want the multi-year process that leads us to that point. Let's start here.” — Rosella Capella Zielinski [38:03]

7. Method, Structure, and Historiographical Reflection

[41:02–46:56]

• The authors explicitly chose to write a narrative-driven, single-case study history book, rather than a more abstract, variable-driven IR monograph:
  • “Most political science books don't do one case...we are so lucky to have to write the book that we wanted to write. And it's a coup…” — Rosella Capella Zielinski [41:02]
  • They credit their analytical framework (outlined in Chapter 2) for helping target relevant archival material—using IR theory for discipline, but not for formulaic structure.
  • Deep gratitude is expressed to archivists, especially during COVID access limitations.

8. Final Thoughts and Contemporary Relevance

[47:16–50:37]

• The authors caution against simplistic analogies but see enduring lessons:
  • Wheat remains geopolitically crucial, as recent events in Ukraine and the global food market underline.
  • The historical experience illustrates both the potential and the limits for states to cede sovereignty for the common good—salient for challenges like climate change and pandemics today.
    • “There are a lot of global challenges today that honestly, to solve them, are going to require global cooperation...this case gives you a clear lesson on both the possibilities for that, but also the limitations to it.” — Paul Poast [47:16]
  • Domestically, Americans are reminded not to take wheat self-sufficiency for granted.

Notable Quotes & Memorable Moments

• “Amateurs study tactics and professionals study logistics.” — Joby Turner [01:46] (framing the episode’s theme)
• “I've never taken wheat for granted again.” — Rosella Capella Zielinski [16:04]
• “It was officially formed in November 1916...bestowed or delegated by the British, the French and the Italians to make all shipping and wheat purchasing decisions on behalf of the Allied Powers.” — Paul Poast [19:34]
• “Once the Americans joined the war...scarcer and scarcer tonnage...[but] the Allied Maritime Transport Council just doesn't have that same extreme levels of authority given to it because the Americans are now on board and they have a little bit of this mine, mine, mine attitude...” — Rosella Capella Zielinski [28:44]
• “I have no doubt that you, like me, are anxious for us to avoid at all costs the mistakes that were made in the last war...” — French Prime Minister to British Prime Minister, 1939, quoted by Rosella Capella Zielinski [38:03]
• “When do you become more than the sum of your parts?...these legacies are a very clear direct line...back to these immediate post war legacies...” — Rosella Capella Zielinski [38:03]
• “We did our best to try to put you in the moment of somebody in 1916 and to try not to make it so dry as sometimes military histories can be.” — Rosella Capella Zielinski [49:56]
