Real-time conflict prediction system that would have detected the Ukraine invasion 72 hours before it happened.
Built for SCSP National Security Hackathon 2026 (Wargaming Track)

Intelligence agencies react to conflicts after they start. The 2022 Ukraine invasion caught the world by surprise — not because the signals weren't there, but because no one was fusing them together in real-time.
Decision-makers need early warning systems that detect threats before escalation.
SENTINEL fuses 5 independent data sources into a single 0-100 threat score, updated every 30 minutes:
| Signal | Source | What It Detects |
|---|---|---|
| 📰 News | GDELT (65,000 sources) | Media coverage spikes, diplomatic tensions |
| OpenSky Network | Military flights, troop transports, evacuations | |
| 🌍 Seismic | USGS | Nuclear tests, artillery barrages, underground activity |
| 📈 Stocks | Yahoo Finance | Defense contractor insider trading patterns |
| ⚔️ Conflicts | ACLED | Ground truth of battles, explosions, territorial control |
Result: When multiple signals align → Early warning before escalation
SENTINEL was tested against 4 major conflicts:
| Conflict | Alert Would Fire | Actual Event | Warning Window |
|---|---|---|---|
| 🇺🇦 Ukraine 2022 | Feb 21, 2022 | Feb 24, 2022 | 72 hours |
| 🇮🇳 Kargil War 1999 | May 1999 | June 1999 | 30 days |
| 🇮🇶 Gulf War 1990 | Jul 31, 1990 | Aug 2, 1990 | 48 hours |
| 🇮🇱 Israel-Iran 2024 | Tracked escalation in real-time | Oct 2024 | Real-time |

SENTINEL follows a three-layer design:
Runs every 30 minutes or on-demand. Calls 5 APIs for 10 global regions, calculates threat scores (0-100), and saves results to threat_cache.json.
Purpose: Collect and process raw intelligence signals
Flask server on localhost:5000. Loads cached data and serves it to the frontend. Provides AI endpoints for conflict briefs, chatbot, and claim verification.
Purpose: Expose data and AI features via REST API
React application on localhost:3000. Displays interactive map, visualizations, AI tools, and historical replays. Reads all data from the backend API.
Purpose: User interface for threat monitoring and analysis
Data Flow: External APIs → Scheduler → Cache → Backend → Frontend
Design Benefits:
- ✅ Resilient (cache prevents demo failures)
- ✅ Fast (no live API delays)
- ✅ Cost-effective (stays in free tiers)
- ✅ Scalable (deploy layers separately)
Data Flow: External APIs → Scheduler → Cache → Backend → Frontend
Why This Design?
✅ Resilient — Cache prevents API failures during demos
✅ Fast — Zero latency for UI interactions
✅ Cost-effective — Minimizes API calls, stays in free tiers
✅ Scalable — Each layer can be deployed independently
