Vivek Ramaswamy, the 38-year-old entrepreneur running for the Republican presidential nomination, has initiated a war against what he views as an outdated, establishment foreign policy. He is deeply skeptical of NATO. He wants to swiftly end the war in Ukraine, detach Russia from China, and compel Taiwan to defend itself without America. He also proposed reducing American financial aid to Israel, a stance long considered politically impossible on the right, before saying he would do so only with Israel’s approval. This week, Ramaswamy attempted to justify such stands with an essay in The American Conservative called “A Viable Realism and Revival Doctrine.”

Invoking Presidents George Washington, James Monroe, and Richard Nixon—whom Ramaswamy has called “the most underappreciated president of our modern history in this country, probably in all of American history”—the article appears to be an effort to lend coherence and gravitas to Ramaswamy’s worldview. It also seems to be an attempt to counter the attack by former United Nations Ambassador Nikki Haley that he has “no foreign policy experience, and it shows.” In the article, Ramaswamy promises to restore American national pride and identity after decades of feckless liberal internationalist and neoconservative policies. “We will be Uncle Sucker no more,” he writes.

It would be foolish to underestimate Ramaswamy, who has vaulted past many of his detractors to become a breakout star in the GOP primary. And at a moment when Republican support for the war in Ukraine is plummeting, his call for retrenchment, much like Donald Trump’s denunciation of the Iraq War in 2016, is perfectly pitched to appeal to the party’s nationalist wing. But just how realistic and viable is his vision?

The truth is that Ramaswamy is slapping the realist brand onto a hodgepodge of policy proposals that are divorced from reality. Realism is about a number of things—the balance of power, national interests, spheres of influence—but one thing it is not about is wishful thinking. Yet that is what Ramaswamy is peddling. His vision is no less dogmatic than the neoconservatism he professes to despise, substituting the belief that America should intervene everywhere with the conviction that it shouldn’t intervene anywhere. And his proposals almost seem calculated to injure, not promote, American interests.

Like more than a few Republicans these days, Ramaswamy is obsessed with China, which he depicts as the locus of evil in the world, and cavalier about Russia, which stands accused of perpetrating war crimes in the heart of Europe. He does not explain how China’s current troubles—a faltering economy, an aging population, grave environmental problems—can be reconciled with his portrait of a totalitarian power about to turn a new generation of Americans, as he averred in a speech at the Nixon library, into “a bunch of Chinese serfs.”

Ramaswamy’s demagoguery about China is reminiscent of the apprehensions voiced by American conservatives after World War II, when the GOP contained an “Asia First” wing, led by Senator Robert A. Taft and others who disparaged American aid to Europe and claimed, improbably, that American military supplies to Generalissimo Chiang Kai-shek would allow him to easily topple the communist dictatorship on the mainland. Ramaswamy seems to want to avert a conflict with Beijing, but his truculent calls for confronting China would render a fresh world war more, not less, probable.

In his American Conservative essay, Ramaswamy lauds Nixon as the president whose foreign policy he most admires. “He got us out of Vietnam,” Ramaswamy writes. Not exactly. As president, Nixon embarked upon the policy of “Vietnamization” to reduce American troops, but he needlessly expanded the war with a secret bombing campaign against Cambodia, where the Khmer Rouge, led by the genocidal Pol Pot, ended up coming to power in 1975. No less addled is Ramaswamy’s grasp of the history of Nixon’s opening to China. He announces that, as president, he would carry out a new version of what Nixon accomplished in 1972 by traveling to China—visiting Moscow in 2025 to create peace with Russia and then “elevate [it] as a strategic check on China’s designs in East Asia.” But Nixon never sought to isolate the Soviet Union; he sought to create a stable equilibrium among the three countries, pursuing what he and Henry Kissinger called “triangular diplomacy.” In addition, Nixon and Kissinger hoped that a web of economic ties between America and the Soviet Union would constrain its propensity to expand abroad—the very approach that Ramaswamy now condemns when it comes to long-standing American policy toward China.

Declaring that “Putin is the new Mao,” Ramaswamy claims that he will be able to woo the Russian leader away from China. He proposes to bow to Russian suzerainty over the territories it controls in eastern Ukraine and oppose Ukrainian membership in NATO “in exchange for Russia exiting its military alliance with China.” But as others have noted, those two countries do not have a military alliance. In any case, Putin has repeatedly displayed no interest in serious peace negotiations over Ukraine, a country that he remains wholly intent on reducing to the status of an imperial Russian colony.

Like Trump before him, Ramaswamy tries to disguise his apparent animus toward democratic countries by scorning what he maintains is Western Europe’s piddling military spending. But Central and Western Europe’s military outlays reached $345 billion last year, almost 30 percent higher than they were a decade ago. The obstacle to real reform, we are told, is an ossified NATO bureaucracy that is pushing liberal internationalist missions whenever and wherever it can. Ramaswamy claims that he would transform NATO into a “strictly defensive military alliance”—as though it were an imperialist power marauding around the world looking for wars to wage.

Ramaswamy’s candidacy has exposed real rifts within the GOP over foreign policy. The Wall Street Journal denounced him for seeking to sell out Ukraine, and National Review asked whether “he’s auditioning for a geopolitical game show instead of the presidency of the United States.” To some extent, his comments can be dismissed as bluster. But he and his fellow self-proclaimed realists—a cluster of activists and thinkers at places such as The American Conservative, the Claremont Institute, and the Heritage Foundation—are responding to a genuine, if dismaying, phenomenon in the American electorate. No one is trying to exploit it more audaciously than Ramaswamy, who continues to offer chimerical promises about restoring America’s national identity. We now know better than to disregard such salesmen.
