Cambodian rice farmer Mao Sary pressed his hands together in a show of gratitude.

He was packing up his belongings in the makeshift cart that had brought his family to safety when fighting with Thailand, a longstanding U.S. ally, broke out in July. Now, after a ceasefire facilitated by U.S. President Donald Trump, they were preparing to return home from the Buddhist pagoda where they had sheltered.

"I would like to thank Donald Trump for helping Cambodia and helping Cambodian people to move back to their villages," he said. "I appreciate it so much."

Other displaced farmers echoed Sary's approval of the U.S. president, half a world away. Cambodia's government has nominated Trump for the Nobel Peace Prize.

Of all the conflicts Trump has involved himself in since returning to the White House, the skirmishes over a colonial-era border dispute between Thailand and Cambodia may be the smallest. But just as much as his role in the Ukraine war or the Middle East, his efforts at strongman diplomacy are another indication of the abrupt shift away from a postwar liberal world order in which institutions and international law—in theory if not practice—took precedence over pure might.

"Trump's involvement demonstrates a preference for state-dominated realism by the stakeholders involved in these crises, especially for direct great power arbitration rather than using international institutions such as the U.N.," said Paul Chambers, visiting fellow at the ISEAS–Yusof Ishak Institute in Singapore.

"It places and prioritizes powerful states as the raw handlers of global power rather than international institutions," he told Newsweek.

And geopolitical calculations are also shifting.

After years of getting closer to Beijing and being at odds with a United States that had lectured them over human rights and backsliding on democracy, Cambodia's leaders could hardly have been more effusive in their praise for a U.S. president.

"This is but one example of President Trump's exceptional achievements in de-escalating tensions in some of the world's most volatile regions," said the nomination letter to the Nobel committee from Prime Minister Hun Manet. "His consistent pursuit of peace through diplomacy aligns perfectly with Alfred Nobel's vision—honoring those who have made outstanding contributions to international fraternity and the advancement of peace."

Thai officials have not made a public statement on the Nobel Prize nomination and did not respond to a Newsweek request for comment by publication time.
