At one particularly tense moment, in October 2020, American intelligence reports detailed how Chinese leaders had become worried that President Trump was preparing an attack. Those concerns, which could have been misread, prompted Gen. Mark A. Milley, the chairman of the Joint Chiefs of Staff, to call his counterpart in Beijing to assure otherwise.
“The Taiwan issue has ceased to be a sort of narrow, boutique issue, and it’s become a central theater — if not the central drama — in U.S.-China strategic competition,” said Evan Medeiros, who served on President Obama’s National Security Council.
China’s ambitious leader, Xi Jinping, now presides over what is arguably the country’s most potent military in history. Some argue that Mr. Xi, who has set the stage to rule for a third term starting in 2022, could feel compelled to conquer Taiwan to crown his era in power.
Mr. Xi said Saturday in Beijing that Taiwan independence “was a grave lurking threat to national rejuvenation.” China wanted peaceful unification, he said, but added: “Nobody should underestimate the staunch determination, firm will and powerful ability of the Chinese people to defend national sovereignty and territorial integrity.”
Few believe a war is imminent or foreordained, in part because the economic and diplomatic aftershocks would be staggering for China. Yet even if the recent flights into Taiwan’s self-declared air identification zone are intended merely as political pressure, not a prelude to war, China’s financial, political and military ascendancy has made preserving the island’s security a gravely complex endeavor.
Until recently, the United States believed it could hold Chinese territorial ambitions in check, but the military superiority it long held may not be enough. When the Pentagon organized a war game in October 2020, an American “blue team” struggled against new Chinese weaponry in a simulated battle over Taiwan.
