The most consequential phone calls in modern American civil-military relations were not made to threaten an adversary — they were made to calm one down, and that distinction is precisely what turned a routine act of crisis management into a four-year political firestorm.
Key Points
- General Mark Milley, then Chairman of the Joint Chiefs of Staff, called his Chinese counterpart in October 2020 and January 2021 to reassure Beijing the U.S. had no intention of attacking.
- Milley testified under oath to the Senate that the calls were routine, coordinated with civilian defense officials, and driven by intelligence suggesting China feared an imminent American strike.
- Critics, including former President Trump and several Republican senators, labeled the calls treasonous and demanded investigation; no charges or formal findings of wrongdoing ever followed.
- The episode echoes a long history of back-channel military diplomacy, from Kissinger’s secret 1971 China talks to today’s newly formalized U.S.-China military hotlines.
- In 2025 the Pentagon stripped Milley of his security detail and clearance, even as the department pursued the same kind of direct military-to-military channel with Beijing that had made Milley controversial.
What Actually Happened on Those Calls
The facts are not seriously in dispute. In the closing months of the Trump administration, amid rising U.S.-China friction over Taiwan and the South China Sea, American intelligence indicated that senior Chinese military leaders genuinely believed the United States might be preparing a strike. Milley, acting in his role as the nation’s top uniformed officer, telephoned General Li Zuocheng of the People’s Liberation Army twice — once on October 30, 2020, days before the presidential election, and again on January 8, 2021, two days after the Capitol riot. His message, by his own account and that of General Li’s, was simple: “We are not going to attack or conduct any kinetic operations against you,” and if that ever changed, “I’m going to call you ahead of time. It’s not going to be a surprise”.
Milley did not dispute making the calls; he defended them. Speaking publicly after the calls became national news through Bob Woodward and Robert Costa’s book Peril, he said his task “at that time was to de-escalate”. His office went further, calling the conversations “vital” to “reducing tensions” and “avoiding unintended consequences or conflict,” and stressed they were coordinated through the proper interagency channels rather than freelanced. That coordination claim matters enormously to how the episode should be judged, because a chairman acting alone to countermand presidential authority is categorically different from a chairman executing a sanctioned de-escalation protocol.
A Mechanism Older Than the Controversy
Military-to-military hotlines exist precisely because nuclear-armed rivals cannot afford the ambiguity that ordinary diplomacy tolerates. The concept is not new, and it did not begin with Milley. Henry Kissinger’s secret 1971 negotiations with Beijing — conducted without public knowledge and initially controversial in exactly the way Milley’s calls became controversial — laid the groundwork for Nixon’s historic 1972 visit and the reopening of U.S.-China relations after two decades of silence. History did not remember Kissinger’s secrecy as betrayal; it remembered it as statecraft, because the outcome vindicated the method. The Milley case asks whether a uniformed general, rather than an elected or appointed civilian envoy, should have that same latitude — a genuinely harder question than the treason framing allows.
The broader pattern holds today. In 2025, Secretary of War Pete Hegseth announced that the U.S. and China had agreed to establish formal military-to-military channels explicitly designed for “deconflicting and deescalating any issues” following a Trump-Xi summit. That is, almost word for word, the justification Milley gave for his own calls four years earlier — except this time it was announced publicly, blessed by the administration, and celebrated rather than condemned. The difference was not the substance of the communication; it was who controlled the narrative around it.
The Treason Accusation and Its Thin Evidentiary Record
Trump called the reporting “fake news” and later accused Milley of an act “so egregious” that it was “punishable by death” under the old rules of the military. Senators Chuck Grassley and Jim Banks repeatedly pressed the Pentagon’s inspector general to investigate what they characterized as chain-of-command interference and an effort to undermine civilian control of the military. Conservative commentators and legal advocacy groups argued Milley had improperly restricted presidential authority over the use of force. These are serious allegations, and they deserve to be taken at face value rather than dismissed as partisan noise.
But the specific claim that circulated most widely and did the most damage — that Milley had been formally arrested or charged with treason — was independently checked and found false; no reliable reporting ever supported it, and Milley served out his term and retired on schedule. Milley testified under oath before the Senate Armed Services Committee on September 28, 2021, that the calls were made on instructions to de-escalate, that Trump officials were aware of them, and that he never sought to undermine the commander-in-chief. Sworn congressional testimony is not proof of innocence in some absolute sense, but it is a materially stronger form of evidence than a book excerpt or a cable-news accusation, and no subsequent investigation has produced documentary contradiction of that testimony.
Where the Channel Actually Failed
The more instructive criticism of Milley’s back-channel diplomacy is not that it was treasonous but that it is fragile and asymmetric — dependent entirely on Beijing’s willingness to pick up the phone. That weakness showed itself starkly in August 2022, when Pentagon officials tried repeatedly to reach their Chinese counterparts during the crisis surrounding House Speaker Nancy Pelosi’s visit to Taiwan, and the calls simply went unanswered. A hotline that only works when the other side wants it to work is not a hotline in any meaningful strategic sense; it is a favor, revocable at will. That episode is arguably a stronger indictment of the concept’s reliability than anything alleged about Milley’s motives.
What the Aftermath Signals
In 2025, the Pentagon under the new administration rescinded Milley’s security detail and clearance, a punitive step that followed years of public criticism from Trump and continued unresolved calls from Senate Republicans for a formal accounting. Whatever one concludes about the propriety of the original calls, the fact that the department simultaneously moved to punish Milley while adopting the identical de-escalation mechanism he used — now rebranded as an official hotline — is the clearest evidence available that the substance of his actions was never really the problem. The problem was who authorized it, under what political circumstances, and whether an unelected general should ever hold that kind of discretion during a period of presidential transition and civil unrest.
That is the durable lesson here, and it will outlast this particular controversy. As long as nuclear-armed powers maintain standing militaries capable of catastrophic miscalculation, someone in uniform will need a direct line to the other side’s uniform. The question every future crisis will force policymakers to answer is not whether such channels should exist — the 2025 U.S.-China hotline agreement settles that they will — but who controls them, under what oversight, and how the public should judge a general who uses one during the most volatile handoff of power in modern American history.
