The Constable or the Conqueror? Debating U.S. Intervention

Color political cartoon from Judge titled “A Thing Well Begun Is Half Done.” A caricature of President William McKinley stands on a map of North and Central America, using a shovel like a spade to dig a canal across the isthmus between the Atlantic and the Pacific. U.S.-flagged ships crowd both coasts, and American flags mark places like Cuba, Puerto Rico, and the Philippines. In the background, Uncle Sam stands near the U.S. Capitol carrying tools and a flag, implying Washington is backing the project as part of national expansion.

This post first appeared on the Library of Congress sponsored – Teaching with Primary Sources (TPS) Teachers Network, where I contribute as an online content creator. I’m reposting it here for readers of peterpappas.com who may not be in that space. A quick note on the present day hook. I’ve got strong opinions about Trump’s latest action in Venezuela. For the TPS version, I kept the framing usable in a classroom, with a neutral tone and a focus on what the historical cartoons reveal about recurring arguments for and against U.S. intervention. If you teach, I’d recommend joining the TPS Teachers Network. It’s free, and it’s a steady stream of smart lesson ideas, primary sources, and teacher-tested activities.

Album Description: This collection of political cartoons from the late 19th and early 20th centuries illustrates the polarized debate over U.S. foreign intervention. From the “Big Stick” of Theodore Roosevelt to anti-imperialist critiques of American expansion, these images reflect the same tensions we see in modern headlines regarding Venezuela.

The 2026 capture of Nicolás Maduro serves as a powerful reminder of the long history of U.S. interventions in the Western Hemisphere. For over a century, the United States has taken direct action in the region for a variety of reasons – ranging from security and stability to self-serving economic and political interests – with results that have been viewed as both beneficial and detrimental. This album invites students to use their historical thinking skills to examine how the visual rhetoric of the past mirrors today’s geopolitical realities, encouraging them to analyze the motivations and consequences of American foreign actions across different eras.


Lesson Plan: Historical Thinking & Foreign Policy

  • Grade Level: 9-12 (US History / Government)
  • Essential Question: Does the United States have the right to intervene in the affairs of other nations?
  • Historical Thinking Skills: Contextualization, Corroboration, and Sourcing.

1. Essential Question

Briefly mention the recent news regarding U.S. military interests and diplomatic pressure in Venezuela. Ask students: “When we see the U.S. getting involved in South America today, are we seeing a new policy, or the continuation of a 120-year-old debate?”

2. Analysis Activity: The “Spectrum of Intervention”

Divide the class into small groups and assign each group 2–3 cartoons from the album. Ask them to analyze the cartoons using the LOC Primary Source Analysis Tool.

The Categorization Task: Students must place their cartoons on a spectrum on the whiteboard/digital board:

  • The “Pro-Intervention” Side: Cartoons that depict the U.S. as a “World Constable,” a “Rescuer,” or a “Teacher”.
  • The “Anti-Intervention” Side: Cartoons that depict the U.S. as an “Oppressor,” “Greedy,” or “Overburdened”.

3. Analyzing Key Arguments (Corroboration)

Once the cartoons are categorized, have the students identify the core arguments used by the artists.

  • Arguments FOR Intervention:
    • Maintaining order/stability in the hemisphere.
    • Humanitarian duty to “save” people from bad actors/dictators.
    • Advancing U.S. economic interests and trade routes.
  • Arguments AGAINST Intervention:
    • Violation of the “consent of the governed.”
    • The high cost (blood and treasure) of empire.
    • The hypocrisy of a former colony (the U.S.) becoming a colonizer.

Exit Choice Board: The Venezuela Debate

Instructions: Select one of the following options to demonstrate your understanding of the historical roots of the current U.S. intervention in Venezuela.

Option 1: The Visual/Creative (The “Modern Big Stick”)

  • Task: Create a rough sketch or a detailed “visual metaphor” for U.S. foreign policy in 2026.
  • Requirement: Your drawing must incorporate at least one specific symbol or “character” found in the historical cartoons.
  • The Goal: Show whether you think the 2026 intervention is a “Rescue”  or an “Expansion”.

Option 2: The Verbal/Performative (The “60-Second Briefing”)

  • Task: Record a one-minute “Voice Memo” or perform a live “Elevator Pitch” to a member of the Senate Foreign Relations Committee.
  • Requirement: You must cite one specific historical cartoon from the album to support your stance on the current military strikes.
  • The Goal: Use the primary source as a “precedent.” For example: “Senator, we are repeating the mistake shown in the 1899 cartoon ‘School Begins’ by assuming we can ‘teach’ democracy through force…”

Option 3: The Written/Analytical (The “Social Media Fact-Check”)

  • Task: Write a “Community Note” or a “Thread” (3 posts) responding to a hypothetical modern headline supporting or opposing the capture of Maduro.
  • Requirement: Use two cartoons to show how this debate is not new.
  • The Goal: Use the skill of Corroboration. Show how the historical arguments are being echoed (or contradicted) by the arguments used for Operation Absolute Resolve today.

Curating Historical Content

Curating Historical Content

Teachers are looking for resources for online instruction. So I am reposting lessons from my Social Studies Methods Course at the University of Portland’s School of Education. See original post here.


Most materials are in the public domain if they were produced before 1923. I see this as roughly equivalent to everything that happened in the world up to and including World War I! If you’re looking for newspaper articles in Chronicling America, for example, you will note that coverage ends in 1922. 

Primary sources produced by the federal government are normally in the public domain both before and after the magic copyright date of 1923. That explains why we as teachers can use the fabulous oral history interviews of former slaves collected between 1936 and 1938 by workers from the Federal Writers’ Project.

Image Detective Activity (inspired by Crop It lesson)

Being able to find and curate historical source material is a foundation of historical thinking. This activity merges three instructional goals: finding / curating historical sources, looking closely at historical sources and using WordPress tools to add images and hyperlinks. It will help students learn how to find material for future lesson design activities. 

  1. Find 3 historical images – use these historical archive sites
  2. For each image: provide full image with citation in hyperlink back to source
  3. Then add a of crop area of each image to show one of the following clues (add clue in the image caption) Tips on how to crop an image
  4. Put all content into a post. Give it a clever title. Include a featured image.
  • who or what this image is about.
  • where this takes place.
  • when this happened or was created.
  • what is the creator’s point of view or purpose.
  • something I have a question about

Example: Image with two crops

African American Soldiers in an Automobile Source
When? It’s an upside down 1919 NYS license plate.
I think they are returning Black WWI soldiers in a parade.
These Black soldiers are being honored in a parade. Knowing 1919 is in the Jim Crow / KKK era,
I wonder what else faced them back in America?

In class practice images. Choose one. Add to a sample post. Include source hyperlink and crop with comment.

Sample student work from this assignment
Notice some of the fashion choices of these women. For example, all but one of these women have chosen to wear pants rather than skirts. Do you think this was a normal clothing choice for women in the 1920s? Could their outfits be related to the social statement they are making?

Close Reading Historical Documents

Close Reading Historical Documents

Teachers are looking for resources for online instruction. So I am reposting lessons from my Social Studies Methods Course at the University of Portland’s School of Education. See original post here.


Teachers can use historical documents to build literacy skills in a content area while empowering students to be the historian in the classroom. But document-based  instruction in this context requires four key elements to be successful:

  1. The right documents. (shouldn’t be reliant on background knowledge)
  2. Knowing how to “read” the historical document.
  3. Letting students discover their own patterns, then asking students to describe, compare and defend what they found.
  4. Basing the task on enduring questions, the kind that students might actually want to answer.

In Class 7 we will practice some strategies for assisting students to more closely read a document (in all their multimedia formats) by answering three Common Core questions. Broad version:

  1. What does it say?
  2. How does it say it?
  3. What’s it mean to me?

More specifically, what do we mean by close reading? Teachers can guide students with scaffolding questions that explore “texts” (in all their forms).

Key Ideas and Details:

What does the text say? Identify the key ideas. What claims does the author make? What evidence does the author use to support those claims?

Craft and Structure:

Who created the document? What’s their point of view / purpose? How did the text say it? How does it reflect its historic time period?

Integration of Knowledge and ideas: 

Distinguish among fact, opinion, and reasoned judgment in a text. Recognize disparities between multiple accounts. Compare text to other media / genres. How does it connect to what we’re learning? 

And what’s it mean to me?
