The Real Thucydides Trap Overconfidence could draw America and China into a war.

The United States and China each believe that they can use new technologies to overcome the other’s advantages—and “the more they indulge this prewar hope, the more likely they are to find themselves in a protracted conflict,” writes Joshua Rovner.

"Autonomous weapon systems bring many risks and concerns, but they also present an opportunity to, in specific cases, wage more discriminate forms of war—an opportunity to master and mitigate the scourges of war." by Nathan Wood from his article, "Bombs, Bots, and the Principle of Distinction . . ."

"Autonomous weapon systems bring many risks and concerns, but they also present an opportunity to, in specific cases, wage more discriminate forms of war—an opportunity to master and mitigate the scourges of war." by Nathan Wood from his article, "Bombs, Bots, and the Principle of Distinction . . ."

Can autonomous weapons make war less brutal?

Instead of viewing autonomy solely as a risk, Nathan Wood (@woodnathang.bsky.social) posits that these systems—when used within the correct parameters—offer a pathway to more discriminate and legally compliant warfare. tnsr.org/2025/12/bomb...

How has teaching about 9/11 changed since 2001? We asked educators. Once a shared experience, the day has slipped into history for students, and even teachers, who weren't yet born when the attacks happened.

Strategy and Grand Strategy Wartime leaders should understand the link between violent means and political ends. They should also have a sense of how strategic decisions will affect the post-war peace. Yet they often fail to make these connections. Mistaking strategy for grand strategy, or misunderstanding the relationship between them, can frustrate soldiers and statesmen alike. Sometimes it can lead to national ruin.
