A new CFR survey of historians examines which decisions have left the greatest legacies, for better or worse.

The United States marks the 250th anniversary of its founding this year. Since 1776, the country has grown from a fragile union of small, loosely connected states with a questionable future to a global superpower that wrote the rules for the world order. Throughout it all, the United States has had to navigate a challenging international environment. Looking back at that history, some U.S. policies have made Americans proud. Others have not. So which foreign policy decisions would top a list of the best? Which would top a list of the worst?

Students often asked me those two questions when I was a college professor teaching U.S. foreign policy. To my good fortune, I recently had the opportunity to pose both questions to professional historians. A new webpage providing the results of that survey, along with a deep dive into the ten decisions that topped the Best and Worst lists, went live this morning. They say a picture is worth a thousand words, so here is a video counting down the top ten Best decisions:

And here is a video counting down the top ten Worst decisions:

A bit of background about the survey. I polled members of the Society for Historians of American Foreign Relations (SHAFR), the world’s foremost professional association dedicated to the study of the history of American foreign relations. The survey ran from October 5, 2023, through November 5, 2023. The survey provided SHAFR members with a list of 120 foreign policy decisions running from the start of the American Revolution through the end of the first Donald J. Trump administration. The survey asked SHAFR members to select and rank ten decisions from the list that in their “judgment did the most to advance U.S. national interests and values.” The survey then asked SHAFR members to review the same list and select and rank ten decisions that in their “judgment did the most to harm U.S. national interests and values.”

I compiled the list of 120 decisions with the help of an advisory committee composed of SHAFR members. The survey did not seek to assess the quality of military decisions made during wartime (e.g., the D-Day invasion) or to evaluate decisions about organizational arrangements within foreign policy and national security establishments (e.g., the creation of the Foreign Service). The decisions the survey assessed could have been made by the president, the Senate, Congress, or the president and Congress (or Senate) acting together. The website contains a fuller description of the rules that guided the creation of the decision list that the survey used.

Roughly 350 verified SHAFR members completed the survey. Like the AP poll of college football and basketball teams, the website rankings are a weighted tabulation of the raw results. A decision with a ranking of one received ten points, a decision with a ranking of two received nine points, and so forth, with a decision ranked ten receiving one point.

There’s a lot to chew over and even disagree about in the survey results. Lists are, if anything, an invitation for a conversation, and hopefully a productive one at. I will share my thoughts on the lists in subsequent posts. For now, I encourage you to check out the webpage, which tells the history of each decision on the two top ten lists and provides a rich array of links to relevant primary documents, books, articles, documentaries, podcasts, and timelines.
