From Argentina to Japan, MAGA is going global.

President Donald Trump’s slogan has long been “America First,” and his movement is all about making America great again — language the president’s foes misunderstand as meaning “isolationism.”

In fact, strengthening America requires strengthening our friends as well — and Trump sets an example for those leaders in Latin America, Asia and Europe who want to make their nations great again, too.

There’s no paradox here:

The “liberal international order” was a suicide pact, building up China while wearing down America — and the system perversely incentivized our friends to prioritize welfare spending over national security needs.

The alternative to that old, failed order isn’t anarchy or Chinese hegemony; it’s cooperation among stronger nations that take their responsibilities — to their own people and to Uncle Sam — more seriously.

Japan is a case in point. Its new prime minister, Sanae Takaichi, represents a right turn for the dominant Liberal Democratic Party, which is Japan’s leading conservative party.

More than 80 years after the end of World War II, Japan remains constitutionally forbidden to rearm: It has defense forces but not true military.

Takaichi belongs to a wing of the Japanese right that would change that — and thereby make Japan no threat to anybody else but a better ally for America.

The superpower danger in the Pacific today comes from Beijing, and the more constrained Japan is, the less constrained that China is.

Takaichi is a protege of Shinzo Abe, who was prime minister during Trump’s first term and had a uniquely strong bond with him. As the first woman to lead Japan, she’s also drawn comparison to Britain’s Iron Lady of the 1980s, Margaret Thatcher.

Tariffs that serve America’s industrial policy put a strain upon trading partners like Japan, of course — although the land of the rising sun has long practiced its own forms of industrial and agricultural protection.

Trump not only shows leaders like Takaichi that boldness can succeed in throwing out the political establishment’s playbook; his return to power prods allies like Japan to pick leaders simpatico with his right-leaning nationalist worldview.

Right-of-center, anti-establishment politics also plays well for Trump-friendly leaders at home, both with voters and the stock market.

Half a world away, the success of President Javier Milei’s right-leaning party in Argentina’s midterm elections Sunday produced a similar result, with stock indexes booming.

It baffles Trump’s critics that America’s self-declared “Tariff Man” can have such good relations with Milei, a self-described “anarcho-capitalist.” But Trump thinks in terms of interests, not ideology, and it’s in America’s interests that Milei succeed in making Argentina freer, more prosperous and friendlier to us.

There’s no contradiction in nationalists from different nations working in parallel to make their own countries stronger individually and more secure collectively.

Likewise, there’s nothing strange about populist reformers from different places with different needs having sympathy for one another

Bringing different philosophies together to advance shared interests is simply the art of the deal. Trump’s the master of that.

They’re advancing a global realignment that will contribute to making America great again, even as it makes their own nations greater as well.
