Throughout history, powerful leaders have frequently spoken of peace even as they engaged in conflict or expansion. This pattern appears in ancient Rome and continues into the present day. In January 2026, U.S. President Donald Trump expressed frustration over not receiving the Nobel Peace Prize, stating that he no longer felt bound to focus solely on peace, though it would remain a priority. He made this comment amid reports of plans to take control of Greenland and ongoing military actions elsewhere. Similar rhetoric has marked his second term, where claims of ending wars coexist with new interventions. Scholars of Roman history note that such language often serves to justify aggression or mask its effects. The Roman historian Tacitus captured this idea in the first century CE when he wrote that conquerors call theft, slaughter, and plunder by the name of control, and when they create a wasteland, they call it peace. This observation from nearly 2,000 years ago raises questions about how the word peace can function as a tool in the hands of those who hold military power. Examining this through Roman examples and recent events shows a consistent thread: talk of peace can accompany, distract from, or even enable acts of war.
How Did Ancient Romans Use the Language of Peace to Justify Conquest?
In Roman imperial times, leaders presented military victories as the path to lasting peace. The Altar of Augustan Peace, dedicated in 9 BCE, stands as a clear example. Emperor Augustus built it after winning civil wars and foreign campaigns. The monument’s friezes show the goddess Roma seated on war spoils, linking peace directly to Roman dominance. For Augustus, peace meant the end of opposition to his rule, achieved through force. Tacitus, writing around 98 CE in his work Agricola, placed a sharp critique in the mouth of Calgacus, a Caledonian leader facing Roman invasion. Calgacus described Roman actions as theft, slaughter, and plunder disguised as control, and their devastation as peace. This speech came before the Battle of Mons Graupius in 83 CE, where Romans crushed local resistance in northern Britain. Tacitus, himself a Roman senator and governor, used an outsider’s voice to expose the gap between imperial claims and reality. He repeated similar ideas elsewhere in his writings, such as in the Histories and Annals, where threatened groups saw Roman peace as the greatest danger to their way of life. This rhetoric helped legitimize expansion by framing it as a civilizing or stabilizing force. It normalized conquest by turning violence into a necessary step toward order. The pattern shows how those in power could redefine peace to suit their goals, often at the expense of those on the receiving end.
What Parallels Exist in Modern Uses of Peace Rhetoric?
Recent events illustrate how the same dynamic persists. In late 2025, Trump declared his New Year’s resolution for 2026 as peace on Earth. Days later, U.S. forces conducted air strikes in Venezuela, leading to the capture of President Nicolas Maduro and reports of around 100 deaths. The action aimed to secure oil reserves and address drug concerns, but it drew criticism for escalating conflict. Earlier, in June 2025, bombings in Iran were announced with a message celebrating peace. Yet seven months on, the Iranian government faces protests, and further military options remain under consideration. In Gaza, Trump chairs a Board of Peace to oversee a ceasefire and new governance, claiming credit for ending one of eight wars he says he stopped. However, from October to December 2025, Israeli attacks killed 414 Palestinians and injured 1,145, showing ongoing violence despite the ceasefire label. At home, increased ICE enforcement has led to deaths in custody and during protests. These examples show a pattern where aggressive actions accompany strong peace claims. The awarding of a FIFA Peace Prize to Trump in December 2025 and his association with the U.S. Institute of Peace add to the contrast. Like Roman emperors, modern leaders can use peace language to present force as protective or inevitable, shaping public perception of their actions.
Why Does This Rhetoric Persist Across Centuries?
The staying power of such language comes from its ability to serve multiple purposes. It reassures domestic audiences that actions serve a higher goal beyond conquest. It deflects criticism by shifting focus from violence to stability. It justifies expansion as a contribution to order rather than disruption. Tacitus recognized this when he had Calgacus describe Roman peace as a wasteland. The phrase has echoed through time, appearing in Robert Kennedy’s 1968 speech on Vietnam, Seamus Heaney’s 1974 poem on Ireland, and even modern media critiques. Its relevance endures because it highlights a fundamental tension: those who hold power often define peace on their terms, which may mean silence from opponents rather than mutual agreement. In multipolar times, when military actions carry global risks, the rhetoric becomes even more significant. It can mask intentions, build support, or prepare the ground for further steps. Understanding this pattern helps explain why declarations of peace sometimes precede or accompany escalation. It also prompts questions about how genuine peace efforts differ from those that serve strategic aims.
The use of peace rhetoric from ancient Rome to the present day connects leaders across eras who face similar pressures to explain force. Tacitus’ words remain sharp because they expose how language can reshape reality for those in power. In 2026, as military actions continue alongside claims of peace, the gap between words and deeds invites close examination. Recognizing this long-standing practice does not end conflicts, but it equips observers to distinguish between genuine efforts at resolution and those that use peace as a cover for other goals. The persistence of the pattern suggests that true peace requires more than words—it demands actions that match them.
