DecisionsAtWar

Target user

students and curious adults who want a real understanding of modern military history

Features
  • Interactive timeline of presidential decisions with linked primary-source memos and declassified documents
  • 'What was the alternative?' branching points at each major decision so you can replay the tradeoffs
  • Competing perspectives filter — military, diplomatic, regional, and civilian voices side by side
  • Curated learning paths: 15-minute primer, semester deep dive, or current-conflict update
Why now

The NPR piece captures a moment where three major U.S. wars are being openly compared and questioned. Public appetite to actually understand these conflicts — not just react to headlines — is clearly there, and current events make the topic urgent rather than purely historical.

Demand
6/10

The HN/NPR-style longform appetite exists but this is a niche within a niche — adult learners wanting to deeply understand specific U.S. wars is a real but modest audience, not a mainstream one.Top History Apps for Students - EducationalAppStore

Whitespace
7/10

HistoryForge.app uses the exact same 'interactive scenario + primary source reveal' format but covers Caesar, the Black Plague, fall of Constantinople — it does NOT cover modern U.S. wars, leaving the specific niche open.HistoryForge — Interactive History ScenariosInteractive History Scenarios — Play the Decisions That Shaped the World

Monetization
3/10

Free government primary-source tools (DocsTeach) and free podcasting on war decision-making set a $0 anchor; niche military-history consumers rarely pay premium subscriptions and existing education platforms (MasterClass, Wondrium) command modest prices only with broad catalogs.DocsTeachHistoryForge — Interactive History Scenarios

Longevity
7/10

Modern U.S. wars (Vietnam onward) are settled history with stable primary sources — evergreen — though topical urgency driven by current events will fade.

Feasibility
6/10

Decision-tree scenario authoring with embedded primary sources is well-understood tech (HistoryForge proves the pattern works) but writing deep, balanced content for multiple wars is labor-intensive content work.Activity Tool Instructions - DocsTeach
