Diplomacy has always depended on signalling. What has changed is the speed, scale, and permanence of those signals, as social media brings publics into the space of negotiation.

At 3.35 pm on 10 May 2025, Pakistan’s Director General of Military Operations called his Indian counterpart. They agreed that firing and military action on land, in the air and at sea would stop at 5 pm. The guns were to fall silent in eighty-five minutes. The argument over who had silenced them began almost at once. At 5.25 pm, twenty-five minutes after the halt was due to take effect, President Donald Trump announced a “full and immediate ceasefire” on Truth Social and credited American mediation.

India said the agreement had been reached in the military call. Trump’s post told a different story, one in which American mediation had produced the result. That gap between arranging an outcome and owning its story is where diplomacy now meets the platform. Calls, intermediaries and rooms continue to produce terms. Social media changes the space around the talks: who witnesses a signal, who can punish retreat, and how quickly an exploratory position hardens into a public test of nerve.
