Not Just an Island: Why Geography Should Not Drive U.S. Taiwan Policy

The article argues that Taiwan's position in the first island chain should not be the main reason for American support of the island's security.

Why it matters: The article bears on the security theme by questioning whether geographic arguments strengthen or weaken deterrence in the Taiwan Strait.
