What makes just 16 missiles such a deadly threat in the South China Sea

Reuters – James Holmes writes that “In a move that should surprise precisely no one, China’s People’s Liberation Army (PLA) has positioned surface-to-air missiles (SAMs) on one of its South China Sea islands — namely Woody Island, home to Sansha, the administrative capital for the islands, atolls, and other geographic features Beijing claims in the Paracels and Spratlys. For Beijing this move makes eminent sense on many levels: it constitutes yet another reply to American and Southeast Asian challenges to its claims of “indisputable sovereignty” over most of the South China Sea.”
