The Trump factor is shaping global politics, one election at a time — just not necessarily to the president’s taste.

In major votes in Canada and Australia over the past two weeks, centrists saw their fortunes revived, while parties that had borrowed from the MAGA playbook lost out.

President Trump has been back in power for only three months, but already his policies, including imposing tariffs and upending alliances, have rippled into domestic political battles around the world.

While it is too soon to say that anti-Trump forces are on the rise globally, it is clear that voters have Mr. Trump somewhere on their mind as they make decisions.

Political cousins

Canada and Australia share a lot in common: a political system, a major mining industry, a sovereign in King Charles. Now they also share a remarkable political story.

In both countries, before Mr. Trump was inaugurated, the center-left ruling parties had been in poor shape and appeared poised to lose power. The front-runners in polls were the conservative parties, whose leaders flirted with Trumpian politics both in style and in substance.

When Colombia signed a landmark peace agreement with rebels in 2016, it was celebrated internationally for ending a war that had ravaged much of the country for decades. The United States bolstered the peace efforts, helping displaced farmers return to their land and helping prosecute war crimes.

Now, support from the U.S. government — the agreement’s biggest foreign economic backer — has vanished.

As the Trump administration has withdrawn most foreign assistance globally, including dismantling the U.S. Agency for International Development, it has undercut a deal designed, in part, to curtail the flow of drugs to the United States.

“This puts wind in the wings of armed groups,” said León Valencia, director of the Bogotá-based Peace and Reconciliation Foundation, an organization that works on post-conflict issues and had received U.S. funds. “They can tell demobilized guerrillas or victims that the government signed a peace agreement and didn’t keep its promise.”

Since 2001, U.S.A.I.D. has spent more in Colombia than any other South American country, about $3.9 billion.

The writer Isaac Babel is memorialized in the act of creative thinking, eyes on the horizon and pen resting on a stack of paper, in a bronze statue in downtown Odesa — his home city on Ukraine’s Black Sea shore.

The statue may soon be dismantled. To Ukrainian authorities, it is a threat that must be eliminated under a so-called decolonization law ordering the removal of “symbols of Russian imperial politics” to protect Ukrainian culture. The law ensnared the statue of Babel, who served in the Soviet Red Army and built part of his literary career in Russia early last century.

The planned removal has prompted strong pushback from many Odesa residents. They argue that in his classic “Odessa Stories” and elsewhere, Babel’s writings about the city’s Jewish heritage and its gritty world of smugglers and artists of every ethnicity helped make Odesa famous and showcased its multicultural identity.

Much as they oppose Russia’s war, they fear that the law will erase Odesa’s character. “You can’t remove Babel,” said Antonina Poletti, 41, the editor of a local news outlet and a sixth-generation Odesan. “If you remove him, you remove the soul of the city.”

The city is already enduring the ordeal of Russia’s invasion, with drones and missiles hitting it every other night. Now a cultural battle is dividing Odesa, with the Babel statue a flashpoint. The spark was the decolonization law, which was part of a broader effort in wartime Ukraine to sever ties with Russian heritage and build an identity free of its influence.
