Lesson Plan: When Eisenhower Sold the Pound

Overview

• Grade Level: AP US History, AP European History, AP World History (Modern), AP Comparative Government, IB History, undergraduate introductory international relations.

• Time Required: Bell-ringer (10 minutes with audio); single-class structured lesson (50 minutes); extended option (two 50-minute sessions or one 90-minute block with primary-source work).

• Historical Period: October 1956 to January 1957 (the Suez Crisis and its political aftermath in London and Washington), within the longer arc of post-1945 alliance management.

• Modern Connection: US Defense Secretary Pete Hegseth's 1 May 2026 order to withdraw approximately 5,000 American troops from Germany, four days after German Chancellor Friedrich Merz publicly criticised US strategy in the Iran war.

Learning Objectives

By the end of this lesson, students will be able to:

1. Reconstruct the chronology of the 1956 Suez Crisis from the Anglo-French-Israeli invasion (29 October to 5 November) through the British ceasefire (6 November), the full withdrawal (22 December), and Eden's resignation (9 January 1957).

1. Explain the financial mechanism by which the United States Treasury, under Secretary George Humphrey, used pressure on the British pound and a blockade of IMF support to force a British ceasefire and withdrawal.

1. Compare the divergent strategic conclusions drawn from Suez by Britain (Macmillan and the Polaris-era special relationship) and France (de Gaulle's Force de Frappe and 1966 NATO withdrawal).

1. Evaluate the May 2026 US troop-withdrawal decision against the Suez precedent: identical structural play, different lever (legions, not currency), and assess where the parallel illuminates and where it misleads.

1. Construct an evidence-based argument about whether American security guarantees to allies should be regarded as conditional or unconditional, and what the implications are for German strategy after May 2026.

Before Reading

Anticipation Questions

1. If a foreign-policy ally publicly criticises your country's strategy in a war it is fighting, what are the legitimate tools available to your government to express its displeasure?

1. Has the United States ever used economic or military pressure to discipline an ally? Name a case if you can.

1. What does it cost a smaller power to be publicly criticised by a great-power ally on which it depends for security?

Key Vocabulary

• Sterling area / sterling securities: government bonds and other instruments denominated in British pounds. Foreign holders of large sterling positions had material influence over the Bank of England's ability to defend the currency's exchange-rate peg.

• IMF (International Monetary Fund): a Bretton Woods institution established 1944 that lends hard currency to member states facing balance-of-payments crises. The United States, then as now, holds the largest single voting share, giving it effective veto over emergency loans.

• Brigade combat team: the principal manoeuvre formation of the modern US Army, typically around 4,000 to 5,000 soldiers, composed of an infantry or armoured brigade plus its enabling units. The withdrawal Hegseth ordered on 1 May 2026 is built around one such brigade combat team.

• Long-range fires battalion: a US Army formation operating land-based long-range precision-strike systems (such as Mid-Range Capability missiles). The battalion previously planned for Germany was to provide a US deep-strike capability into eastern Europe.

• Force de Frappe: the independent French nuclear deterrent, ordered by de Gaulle and operationally deployed from the 1960s onward, designed precisely to free France from dependence on US extended deterrence.

• Special relationship: the term used since the late 1940s for the close UK-US bilateral relationship in defence, intelligence, and nuclear cooperation, typified by the 1962 Polaris Sales Agreement.

• Article 5 (NATO): the collective-defence clause of the North Atlantic Treaty (1949) under which an armed attack on one member is considered an attack on all. The credibility of Article 5 in any given case rests on the visible US troop presence in Europe.

During Reading

Guided Questions

1. Who was George Humphrey, what did he say to Harold Macmillan, and why did the threat carry weight?

1. What did Macmillan see in the Bank of England's reserve figures during the first week of November 1956 that caused him to flip from being the Cabinet's most enthusiastic war hawk to being the loudest voice for an immediate ceasefire?

1. Why does the story argue that Macmillan and de Gaulle drew different lessons from the same crisis, and what were the long-term policy consequences of each lesson?

1. What did Friedrich Merz say on 28 April 2026 that triggered the US troop-withdrawal decision, and why does the article describe the remark as the kind of thing chancellors used to be able to say?

1. The article describes the 1956 lever as the pound and the 2026 lever as the legions. What is structurally similar about the two levers, and what is genuinely different?

After Reading

Discussion Questions

1. Comprehension: Briefly summarise how Eisenhower used non-military instruments to force Britain out of a war Britain had already begun.

1. Analysis: Macmillan was both the most enthusiastic war-hawk in Eden's Cabinet and the first to demand a ceasefire once the financial figures became visible. Was this principled adaptation or political opportunism, and how would you distinguish the two from the historical record?

1. Analysis: The article claims that Brexit can be partly read as a long-delayed assertion of the independence Britain lost in November 1956. Is this argument historically defensible, or is it overreach? What evidence would settle it?

1. Evaluation: Consider the choice that confronts Friedrich Merz in May 2026. He can swallow the criticism and signal alliance reliability, or he can begin to plan as if US protection were conditional. Which choice serves Germany's long-term interests better, and on what assumptions does your answer depend?

1. Debate (genuinely contestable): Are American security guarantees to European allies more credible, less credible, or about the same after the 1 May 2026 troop-withdrawal decision than they were before it? Defend your position with at least two pieces of evidence from the post-1945 historical record.

The Parallel

1. List at least three structural similarities between November 1956 and May 2026 (an ally publicly defies the US foreign-policy line, the US deploys its most painful unilateral lever, the ally's domestic political position is materially affected, the alliance is reshaped going forward).

1. List at least three structural differences. Consider: in 1956 the ally was acting against US wishes; in 2026 the ally was failing to support what the US wanted. The 1956 lever (financial) was reversible; the 2026 lever (troop deployment) is partially reversible over years. The institutions of 1956 (sterling area, IMF) and 2026 (NATO Article 5, US Army Europe) were built for different purposes.

1. The article ends by asking, "What comes next?" Construct two scenarios. In the first, Merz follows the Macmillan path, walks back the criticism, and signals reliability. In the second, Merz follows the de Gaulle path and begins building a German strategic posture less dependent on US protection. Identify the indicators a contemporary observer should watch over the next twelve months to distinguish which path Berlin is on.

Activities

Bell-Ringer (10 minutes)

Play the audio narration of "When Eisenhower Sold the Pound" (approximately 10 minutes). Students take notes on a graphic organiser with three columns: "London 1956," "Berlin 2026," "Same / Different." After the audio, run a 90-second whip-around on a single question: "Are you on Eisenhower's side, on Eden's side, or on both?"

Single Class (50 minutes)

• 0 to 5 minutes: Anticipation questions on the board, students respond on index cards.

• 5 to 25 minutes: Read or listen to the story together. Students mark named historical actors and the institutional levers each one wields.

• 25 to 40 minutes: Small-group work (groups of three or four). Each group is assigned one of the discussion questions and prepares a 60-second response with one piece of evidence from the story and one piece from outside it (a vocabulary term, a primary source, or a current headline).

• 40 to 48 minutes: Groups present. The teacher charts the arguments on the board.

• 48 to 50 minutes: Exit ticket. One sentence: "If you were Friedrich Merz on the morning of 2 May 2026, what is the first thing you say in public, and why?"

Extension Activity

Take-home (multi-day): Students choose one of the following moments in the post-1945 alliance management of the United States and produce a one-page case file: the 1948 Berlin Airlift, the 1956 Suez Crisis (this story), the 1962 Skybolt cancellation and Nassau Conference, the 1966 French withdrawal from NATO command, the 1979 Carter-Schmidt feud, the 2003 Iraq-war Franco-German "axis of weasels," the 2018 Trump tariffs on European steel and aluminium. The file should answer: (1) the trigger, (2) the lever wielded, (3) the constituency the action was meant to discipline, (4) the immediate political result, (5) the long-term effect on alliance structure.

Alternative: Stage a 2 May 2026 Federal Chancellery roleplay. Half the class plays the Chancellor's foreign-policy advisers urging conciliation with Washington (the Macmillan path); half plays the advisers urging strategic autonomy (the de Gaulle path). Assess on whether students reconstruct the actual contemporary arguments (cost of US protection, plausibility of European alternatives, domestic German politics, the Russian threat, the Iran-war ceasefire prospects) rather than importing twentieth-century frames.

Standards Alignment

C3 Framework

• Dimension 1 (Developing Questions): This lesson supports the inquiry arc on whether security alliances are durable structures or contingent arrangements. The compelling question is: "Are American security guarantees a treaty obligation or a discretionary tool?"

• Dimension 2 (Applying Concepts): History (1956 Suez Crisis, post-1945 alliance management), Civics (the legal status of US troop deployments abroad and the limits on executive discretion), Economics (currency pegs, IMF emergency lending, sovereign foreign-exchange reserves), Geography (Persian Gulf, Sinai, NATO eastern flank, US bases in Germany).

• Dimension 3 (Evaluating Sources): The story's evidence manifest provides 17 primary and secondary citations, allowing students to practise verifying narrative claims against authoritative sources (IMF, Wikipedia, Time, CNN, the UK National Archives, Gresham College). Students should be able to distinguish a primary source (Humphrey's recorded private remark) from a secondary one (the IMF Finance & Development retrospective).

• Dimension 4 (Communicating Conclusions): The Federal Chancellery roleplay and the case-file project both require students to construct argument-based products with evidence.

AP Alignment

• AP US History: Period 8 (1945 to 1980), particularly the Eisenhower foreign policy and the management of NATO allies during the early Cold War; and Period 9 (1980 to present) on the post-1989 evolution of the US security relationship with Europe.

• AP European History: Unit 9 (Cold War and Contemporary Europe), specifically the post-Suez reorientation of British and French foreign policy and the long-running debate about European strategic autonomy.

• AP World History (Modern): Unit 8 (Cold War and Decolonization), with focus on the end of the European empires after Suez and the rise of US hegemony in the post-1945 international system.

• AP Comparative Government and Politics: course themes on alliance politics, the role of executive discretion in foreign policy, and the dynamics of asymmetric bilateral relationships.
