President Donald Trump is once again promoting his role as a dealmaker as he attempts to broker an end to war in Ukraine. He claimed Monday that he has already ended six wars in his second term, after a White House meeting with Ukrainian President Volodymyr Zelensky and other European leaders at which Trump pledged to make progress on that effort.

“I’ve done six wars — I’ve ended six wars,” Trump told reporters. “Look, India-Pakistan, we’re talking about big places. You just take a look at some of these wars. You go to Africa and take a look at them.”

The White House has ramped up its public diplomacy over the issue. A statement released earlier this month crowed that “as President Trump has said time and time again, he is the ‘President of Peace,’” and then listed some of the peace deals claimed as part of the record.

The deals Trump cited included peace efforts on six continents between Armenia and Azerbaijan, Cambodia and Thailand, Israel and Iran, Rwanda and the Democratic Republic of the Congo, Egypt and Ethiopia, and Serbia and Kosovo. Officials also took credit for the so-called Abraham Accords, the normalization deals that Trump brokered between Israel and several Arab nations during his first term.

Ceasefires or Deals?

Critics of Trump have argued that, in many of these cases, the president has not delivered lasting solutions but is instead rebranding ceasefires or attempted détentes as historic peace deals. In the case of Israel and Iran, for example, the war halted after a 12-day clash, but the fundamental disagreements over Tehran’s nuclear program persist.

His efforts to broker past deals also show the limits of his approach. His attempted cease-fire between Israel and the Palestinian militant group Hamas fell apart, while his first-term summitry with North Korean leader Kim Jong Un ended with nothing to show for the photo opportunities, as Pyongyang left with a more muscular nuclear force.

In other cases, Trump has managed to broker symbolic peace deals. Earlier this month, Armenia and Azerbaijan signed a White House declaration on agreeing to recognize each other’s borders and rejecting violence. In addition to the U.S.-backed border normalization, the deal also included a U.S.-funded transportation corridor, which the Trump administration is branding the “Trump Route for Peace and Prosperity.” Azerbaijani President Ilham Aliyev said of the agreement: “We believe this is a miracle.” Still, experts say that the more difficult territorial questions remain on the sidelines.

Pressure Tactics in Southeast Asia

In Southeast Asia, Trump’s interventions in violence between Cambodia and Thailand also show his ability to use economic leverage to end conflicts. Fighting that had claimed 38 lives came to a halt after the president sent a warning to both governments that the U.S. would suspend existing trade deals with the countries unless they stopped the bloodshed. The Association of Southeast Asian Nations (ASEAN) helped broker the final deal, but Cambodian Prime Minister Hun Manet still credited Trump with intervening and also nominated the president for the Nobel Peace Prize for “extraordinary statesmanship.”

Trump later intervened in a similar crisis in May, stepping into a border flare-up between nuclear-armed India and Pakistan. Pakistan’s government welcomed Washington’s role in the talks, but India’s government has been more circumspect. The ceasefire on the India-Pakistan border remains fragile, and the long-running Kashmir dispute between the two countries is still on hold, with the potential to flare again.

In Africa, Trump has also tried to take credit for an agreement between Rwanda and the Democratic Republic of the Congo. In that case, the deal established a pledge to recognize borders and a call for militias to disarm and return home. The M23 rebel group immediately rejected the deal, and analysts have raised doubts that the agreement will hold in the long run. Strategic U.S. interests are also in the mix, with the Congo-Rwanda deal serving to strengthen Washington’s position in its contest with China over Africa’s mineral wealth.

Trump’s claims about Egypt and Ethiopia involve their long-running confrontation over the building of a massive dam on the Nile. The Trump administration has pushed the two governments to compromise but has yet to produce a binding agreement.

The U.S. is also touting measures between Serbia and Kosovo that date to Trump’s first term. The two countries remain at odds on most issues, however, and the latest round of talks, hosted by the White House, have been largely driven by the European Union.

Trump’s combative, go-it-alone diplomacy — which has included his tendency to trade in bombastic rhetoric and personal branding at the expense of quieter negotiations — has produced spotty results. Critics have also argued that his gutting of the State Department and cuts to the U.S. Agency for International Development have left America with a weaker ability to turn short-term arrangements into long-term peace.

Still, analysts say his efforts have on occasion been helpful. Celeste Wallander, a former assistant secretary of defense who is now with the Center for a New American Security, told The Diplomat that Trump’s moves to ease tensions between India and Pakistan were “done in a professional way, quietly, diplomatically … finding common ground between the parties.”

As he now applies pressure on Ukraine, the question is whether Trump’s track record is one of durable diplomacy or of temporary fixes. The balance sheet so far is of both: headline-grabbing agreements that fall short of lasting peace, along with a few instances in which U.S. pressure has prevented conflicts from further escalation. Whether those hold is yet to be seen.
