A breakdown of three wars Donald Trump says he has ended

Donald Trump wants to be awarded the Nobel Peace Prize. He has commented on this several times during his latest year in office, and in his efforts to sway public opinion he has presented a list of eight wars he claims to have ended while in office. But has he really ended these wars? Was he involved? Have these conflicts actually ended? And were they wars to begin with?
We are going to dig into three of the eight conflicts in this article and put Trump’s claims to the test.
War no. 1: Armenia–Azerbaijan
Armenia and Azerbaijan fought a large-scale war from September to November 2020 over Nagorno-Karabakh, a disputed mountainous region internationally recognised as part of Azerbaijan. Armenia had, however, controlled much of the area for decades. A peace treaty following the initial fighting in the early 1990s was never achieved, and Azerbaijan never accepted the post-1994 status quo.
The renewed hostilities did come to an end during Donald Trump’s first term, with a ceasefire reached in November 2020. However, the claim that Trump ended the war is not supported by the evidence we reviewed.
The November 2020 ceasefire was the result of diplomacy led by the Russian Federation. Russia brokered the agreement directly and followed it by deploying peacekeeping forces to the region to enforce it. The United States was not a signatory to the agreement and did not play a decisive role in ending the fighting.
The ceasefire ultimately failed. In 2023, the conflict reignited, and Azerbaijan regained full control of Nagorno-Karabakh, effectively ending the region’s autonomous status, which had existed since 1994.
The claim that Donald Trump ended the Armenia–Azerbaijan war is therefore false. While the United States did participate in mediation efforts alongside France through the OSCE Minsk Group, U.S.-led talks did not end hostilities. The fighting only stopped when Russia intervened decisively.
War no. 2: Thailand–Cambodia
A flare-up of long-standing border tensions between Thailand and Cambodia was triggered by the death of a Cambodian soldier during a border skirmish in early 2025. The incident escalated into larger-scale fighting, displacing tens of thousands of people on both sides of the border.
Diplomatic efforts to halt the fighting were led through ASEAN mediation, with Malaysia facilitating peace talks, alongside Chinese diplomatic involvement and direct negotiations between Thailand and Cambodia themselves. These efforts resulted in ceasefires that reduced hostilities, though tensions remained.
Donald Trump’s role in this process was advisory and supportive, but not decisive. He did not negotiate a peace agreement, nor did the United States enforce or guarantee any ceasefire between the two parties. The reduction in fighting was the result of multilateral regional diplomacy, not U.S.-led intervention.
War no. 3: Israel–Iran hostilities of 2025
In June 2025, hostilities broke out between Iran and Israel following airstrikes carried out by the Israeli military. During the same period, the United States also conducted airstrikes against Iranian targets. The confrontation lasted for approximately twelve days and ended as both sides de-escalated amid mounting costs and the risk of wider regional conflict.
Donald Trump publicly announced that a ceasefire had been reached between the two nations. However, no formal peace agreement was signed in the traditional diplomatic sense, and Iranian officials disputed that a binding ceasefire existed on the terms described by Trump.
The only reasonable conclusion is that the claim Trump ended a war between Israel and Iran is, at best, overstated and, at worst, factually incorrect.
After having revisited the actual facts surrounding only three of the eight wars the White House has claimed Donald Trump ended through diplomacy, real doubt must remain about the objective truth behind these claims. Donald Trump reiterated these claims as late as yesterday afternoon at the White House press briefing, including his assertion that he deserved the Nobel Peace Prize for his efforts toward peace. The Nobel Peace Prize for 2025 was awarded to Venezuelan opposition leader María Corina Machado for her work promoting democratic rights and peaceful transition in Venezuela, and she later presented Trump with her Nobel medal in a symbolic gesture. However, the Norwegian Nobel Committee emphasised that the prize and its recognition remain inseparably tied to the original recipient.
