Part I lists and analyzes the cases I identified, then lists several conclusions I was able to draw from my case studies. Those conclusions are:

1. National security considerations have entered the antitrust enforcement process numerous times over the past 100 years.
2. It is rare for the USG to actively use antitrust enforcement to advance unrelated national security objectives.
3. In cases where national security and economic considerations conflict, economics has been given more weight over time.
4. The president plays an important role in reconciling conflicting considerations.

Part II discusses how these conclusions might apply to AI firms in the coming decades.
