Analyst Assessment
Verdict
Edge: Thailand
Thailand possesses absolute conventional overmatch across all military domains, rendering a Cambodian conventional victory virtually impossible. However, a protracted Thai invasion would risk a draining insurgency and severe geopolitical blowback from China.

Wildcards
- Chinese Intervention Cambodia's deep strategic alignment with China means any severe threat to Phnom Penh could trigger rapid diplomatic pressure, economic leverage, or expedited military resupply from Beijing.
- Minefields and Terrain Cambodia remains one of the most heavily mined countries globally. A deep Thai mechanized advance could become severely bogged down by unmapped minefields and dense jungle, neutralizing their armor advantage.
- Domestic Thai Instability Thailand’s complex internal politics, frequent leadership transitions, and ongoing southern insurgency could fracture its unified command structure or sap political will during a protracted conflict.
Outlook
| Scenario | Short war | Protracted war |
|---|---|---|
| Conventional | 🇹🇭 Thailand dominates completely | 🇹🇭 Thailand achieves decisive military victory |
| Hybrid/Asymmetric | 🇹🇭 Thailand absorbs minimal damage | Even Cambodia bogs down Thai forces in costly occupation |
