Resolved: The United States should substantially reduce its military support of Taiwan.

A security debate with reversed sides

Most students assume supporting Taiwan is the "pro-America" side, and this resolution makes them argue the opposite. Pro’s theory is entrapment and spiral. Every arms package feeds Beijing’s story of creeping independence, speeds up its military buildup, and pulls Washington toward a war over an island it has no treaty obligation to defend. Reduction, paired with diplomacy, restores the strategic ambiguity that kept the peace for decades. Con’s theory is classical deterrence: weakness invites the invasion Pro fears, because Beijing acts when it believes the cost is low.

The porcupine question

The best rounds get concrete about what "support" means. Con defends asymmetric "porcupine" capability (mines, anti-ship missiles, air defense) that raises the cost of invasion without threatening the mainland, and argues this is the kind of support that stabilizes. Pro has two choices. It can sweep porcupine weapons into the reduction, which is harder to defend, or it can target the escalatory categories (big-ticket platforms, training entanglement, visible political-military signaling) and claim that cutting those counts as "substantial" without stripping Taiwan’s defenses. Definitional discipline decides a lot of rounds.

Credibility spillover

Con’s biggest impact is systemic. Allies from Tokyo to Manila read Taiwan policy as a measure of American reliability, so reduction triggers hedging, pressure to proliferate, and regional realignment. Pro’s counter is that credibility hawks keep predicting cascades that rarely arrive, and that reducing military support still leaves room for deeper economic and diplomatic ties. In final focus, the war-probability clash usually outweighs everything else, so teams should build their evidence comparison there early.
