Public Support for Collective Defense in NATO during the Second Trump Administration: A Longitudinal Study
Bibliographic record
Abstract
In this project, we will conduct a longitudinal investigation of public views on collective defense in NATO during the second Trump presidential administration (January 2025–January 2029). We will collect survey data three times annually from the following five countries: the United States, the United Kingdom, Canada, Poland, and Germany. Our primary aim is to test whether Trump’s rhetoric and approach to alliance management lead to discernible shifts in public perceptions of and support for collective defense commitments in NATO. On the one hand, some experts argue that Trump’s approach undermines the credibility of U.S. commitments to NATO allies, which could, in turn, erode the credibility of NATO’s system of collective defense as a whole. On the other hand, some argue that Trump’s unconventional approach will force European allies to make major investments in their defense, which could strengthen NATO’s military capabilities and, consequently, enhance the credibility of collective defense commitments. We propose competing hypotheses to account for these countervailing developments (while noting that they could potentially offset one another, resulting in no net change in public views of collective defense). We will also retain the flexibility to conduct ad hoc surveys following significant future events that may plausibly influence public attitudes in this area.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
