Edge: United States
The United States possesses insurmountable qualitative, quantitative, and global-projection advantages, guaranteeing total dominance in the aerospace and maritime domains. While Taiwan cannot win a conventional engagement, its dense, asymmetric "porcupine" defenses would make any physical ground occupation disproportionately costly and drawn out.

Wildcards
- Geography and Urban Density Taiwan’s rugged mountainous interior and dense urban centers severely complicate physical occupation, favoring decentralized, territorial defense.
- Microchip Monopoly Taiwan’s control over the global advanced semiconductor market means kinetic strikes on its infrastructure would immediately paralyze the global—and U.S. domestic—economy.
- PRC Opportunism Any hypothetical US-Taiwan conflict would immediately invite intervention from the People's Liberation Army, instantly forcing the United States into a massive, two-front strategic crisis.

| Conventional | 🇺🇸 United States dominates | 🇺🇸 United States enforces blockade |
| Hybrid/Asymmetric | 🇺🇸 U.S. paralyzes C2 networks | Even Taiwan leverages terrain for attrition |
