President Donald Trump dominated geopolitical discussions at the World Economic Forum in Davos this week, overshadowing traditional business focus with policy announcements while deepening apparent fractures with Western allies. During his roughly 24-hour visit, Trump reversed his earlier threats of tariffs against European countries, agreed to an Arctic security framework with NATO Chief Mark Rutte, and launched a “Board of Peace” to address the Israel-Hamas conflict.

Governor Gavin Newsom of California criticized Trump during the forum, while Ukrainian President Volodymyr Zelenskyy and NATO Chief Mark Rutte praised his efforts to support Ukraine and strengthen Western defense.

Trump’s rapid reversal on Greenland and his new Board of Peace proposal signal a shift toward ad-hoc policymaking, while Canadian Prime Minister Mark Carney’s description of a “rupture” with allies reflects broader concern about the cohesion of Western institutions.

The Greenland Reversal

Trump delivered what the Associated Press described as a “rambling and at times hyperbolic” speech touting America’s global role. His visit marked his third appearance at Davos as president, but unlike previous trips, he faced organized criticism from Newsom, who repeatedly spoke to reporters in the Congress Center.

The most dramatic moment involved Greenland. In the runup to Davos, Trump announced plans to set new tariffs on eight European countries who opposed his takeover bid for Greenland, a semiautonomous territory of NATO member Denmark. Trump had insisted he wanted to get the island “including right, title and ownership.”

By Wednesday, amid an uproar at home and abroad, Trump backed off from his tariff threats. He said he had agreed with NATO Chief Rutte on a “framework of a future deal” on Arctic security, potentially easing tension with far-reaching geopolitical implications.

The Board of Peace and International Reaction

Trump launched his Board of Peace to spearhead efforts at maintaining a ceasefire in Israel’s war with Hamas and eventually help map a future for the war-torn Gaza Strip. The initiative drew support from countries as diverse as Belarus, Kosovo, Indonesia, and Argentina.

Critics opposed the Board of Peace, including longtime U.S. allies in Europe. They rejected Trump’s claim that it could rival the United Nations one day, with some arguing that the better approach would be to reinforce current U.N. structures rather than replace them.

“I think they were trying to duplicate — replicate — what happened when the United Nations came about,” said Amnesty International Secretary-General Agnes Callamard in an interview. “But frankly it was a very poor and sad attempt to repeat what happened in the 1940s.”

Canadian Prime Minister Mark Carney spoke of a “rupture” between the U.S. and its Western allies that would never be repaired, reflecting the depth of divisions exposed at the forum.

AI Takes Center Stage

Artificial intelligence offered an alternative focus at Davos. Billionaire Elon Musk and Nvidia CEO Jensen Huang made their Davos debuts. Musk jetted in with little advance notice, despite previously calling the WEF event “boring.” He discussed robotics and AI’s electricity demands, while offering gentle criticism of the Trump administration for imposing tariffs on Chinese solar panels.

Huang pushed back on concerns that the AI boom might eliminate jobs, saying it would create work for people building out its infrastructure. “Plumbers and electricians and construction and steel workers and network technicians” would be needed, he said.

Anthropic CEO Dario Amodei struck a more cautious note, comparing the Trump administration’s move to green-light sales of an advanced Nvidia chip to “selling nuclear weapons to Pyongyang.”

Former Democratic Congresswoman Jane Harman observed that the forum reflected “two Davoses” — one focused on industrial leaders discussing AI, the other dominated by geopolitics centered on Trump.

Optimism on Display

The broader tone among technology and business executives at Davos was notably optimistic, aligned with the forum’s stated mission to improve the world and promote dialogue. BlackRock Chairman and CEO Larry Fink captured the mood in closing remarks: “I want to end this forum with the quote that Elon Musk said in closing yesterday’s session — that it’s better to be an optimist and wrong than be a pessimist who’s right.”
