There is a particular kind of diplomat who believes every conflict is, at bottom, a negotiation waiting to happen: two parties, a table, and enough incentive to sign. Donald Trump has always been this kind of figure, and his recent moves, brokering an AI safety communication channel with Xi Jinping while simultaneously urging Volodymyr Zelensky and Vladimir Putin to "make a deal" and "settle," reveal a foreign policy philosophy that predates him by centuries. What's striking is not that Trump negotiates. It's that his approach revives a mode of great-power dealing that the twentieth century tried, with mixed success, to replace with something more durable.

The Old Logic of the Deal

Transactional diplomacy is not new; it is, in fact, the default setting of statecraft before institutions tried to civilize it. Consider Bimbisara of Magadha in the sixth century BC, whose rivalry with King Chanda Pradyota Mahasena of Avanti was as bitter as any modern great-power standoff. When Pradyota fell ill with jaundice, Bimbisara did not withhold aid to extract leverage. He sent his own royal physician, Jivaka, to Ujjain. The gesture, half diplomacy and half humanity, helped make peace possible, and Magadha's rise to dominance over some 80,000 villages owed as much to this kind of pragmatic dealing as to conquest. The lesson from ancient India is that transactionalism, done well, can defuse rivalries that ideology alone would prolong indefinitely.

The Sikh misls of eighteenth-century Punjab offer a different but related lesson. Their unity rested not on a permanent constitution but on the gurmatta, a general assembly convened at Amritsar or on the battlefield, where decisions carried religious weight precisely because they were arrived at collectively and reaffirmed each time. Even old sectarian exclusions, against descendants of dissenters like Sri Chand or Prithi Chand, were quietly dropped when practical unity demanded it. Diplomacy here was transactional in the best sense: flexible enough to bend around old grudges when survival required it.

When the Deal Becomes the Problem

But transactional diplomacy has a darker lineage too, and it is this lineage that ought to temper any enthusiasm about Trump's current instincts. Neville Chamberlain arrived in Downing Street in May 1937 with what his biographer Robert Self called "an innate confidence which now bordered on arrogance," and a firm belief that a "general settlement of differences" with Hitler was achievable through negotiation. The result was the Munich Conference of September 1938, three trips to Germany, and a piece of paper that Chamberlain waved as "peace for our time." Hitler treated it with contempt within months. Appeasement remains, in William R. Rock's phrase, "one of the most controversial policies in the history of international relations," precisely because it mistook a dictator's temporary satisfaction for a durable peace.

The failure at Munich wasn't that Chamberlain negotiated. It was that he negotiated from a position where Britain's own military assessed it could not guarantee victory in a short war, and where the deal effectively handed away someone else's territory (the Sudetenland) to buy time rather than security.

Stalin, and the Deal Nobody Saw Coming

The more instructive precedent for Trump's China outreach may be Stalin's diplomacy in 1939. Stalin was no idealist; he was, in the words of historians of the period, "the arch-realist in the Kremlin," and his overriding concern that year was not Germany but Japan, after the Kwantung Army's incursions into Mongolia and a bloody battle with the Red Army in May 1939. Facing the real prospect of a two-front war, Stalin looked at Britain's half-hearted courtship, a low-level diplomat sent by slow steamer, against Germany's full-court press, Ribbentrop dispatched on Hitler's personal plane, and made his calculation accordingly. The Nazi-Soviet Pact of August 23, 1939 was transactional diplomacy at its most cynical, but it was also, from Moscow's narrow perspective, entirely rational.

This is the uncomfortable truth about transactional statecraft: it rewards whoever shows up with the better offer, not whoever has the better cause. When Trump sits across from Xi Jinping and produces an agreement to establish a communication channel for AI safety incidents alongside enhanced military coordination, he is doing something that resembles Cold War arms control more than it resembles ideological confrontation. The 1963 Nuclear Test Ban Treaty and the Moscow-Washington hotline emerged from a similar realist logic: two adversaries who realized, after the Cuban Missile Crisis brought them to the brink, that unmanaged escalation served nobody. A hotline for AI safety incidents is, in spirit, the hotline of 1963 updated for an era where the existential risk is silicon rather than plutonium.

Ukraine: The Deal That Isn't One Yet

Where the analogy strains is Ukraine. Trump's call for Zelensky and Putin to "make a deal" and "settle" treats the war as a transaction between two roughly symmetric parties who simply need to find their price. But Bimbisara's peace with Pradyota worked because it followed genuine parity established through both conquest and diplomacy. Munich failed because Chamberlain negotiated away Czechoslovak territory without Czechoslovakia at the table, mistaking the appearance of resolution for its substance.

The historical pattern here is uncomfortably clear: transactional deals struck over the heads of the smaller or more vulnerable party, rather than with their full agency at the table, tend not to hold. Versailles created a League of Nations meant to enforce collective security, but its authority was undermined from birth by the harshness of the peace it was meant to police; the mandates handed to Britain, France, and South Africa over Germany's former colonies were themselves a form of great-power transaction dressed up as trusteeship, and they satisfied nobody for long.

What History Actually Teaches

None of this means transactional diplomacy is inherently naive. Bimbisara's era shows it can build durable dominance. The Cold War hotline shows it can prevent catastrophe between adversaries who trust nothing but self-interest. Even Britain's own imperial rise in India, as historians of the period note, depended on relentlessly transactional alliance-building: isolating rivals one by one, as Cornwallis did against Tipu Sultan and Wellesley did against the Marathas, while Indian powers, lacking any concept of modern nationalism, frequently aided the British against fellow Indians for short-term advantage. The tragedy of that history is not that the British negotiated. It is that Indian rulers underestimated British strength and never found a mutual basis for unity, allowing transaction to substitute for solidarity again and again.

This is the test Trump's diplomacy now faces on two fronts simultaneously. The China channel on AI safety is a genuinely promising transactional move: narrow, verifiable, mutually beneficial, in the tradition of the 1963 Test Ban Treaty rather than Munich. It manages a risk both sides fear without requiring either to surrender something essential.

Ukraine is different. Urging both sides to "make a deal" risks repeating Chamberlain's error if it means pressuring the weaker, invaded party toward concessions to placate the stronger one, rather than building a settlement Ukraine itself can live with and enforce. The historical record, from Brest-Litovsk in 1918, where a physically overmatched Trotsky was bluntly told by General Hoffman that "the victorious German army stands in your territory," to Munich twenty years later, is unambiguous on this point: deals struck under duress by the weaker party, without genuine reciprocity, tend to be the prelude to the next war rather than the end of the last one.

Trump's instinct for the deal is not new, and it is not automatically wrong. History's verdict on transactional diplomacy depends entirely on whether the transaction reflects real parity and mutual interest, as with Bimbisara and Pradyota, or merely papers over an imbalance of power, as at Munich. The AI channel with Beijing looks like the former. Ukraine, for now, remains dangerously unresolved as to which it will become.
