Initially criticized as isolationist, Donald Trump’s “America First” strategy is now being reevaluated by national security experts, who see it as a robust policy of deterrence. This approach emphasizes strengthening alliances, notably with Israel, rather than withdrawing from international commitments.

Fred Fleitz, who serves as the vice chair of the America First Policy Institute’s Center for American Security and is a former chief of staff at the National Security Council, shared his insights with Fox News Digital. He described the “America First” strategy as a multifaceted approach to U.S. national security—prioritizing a strong defense, decisive leadership, avoidance of unnecessary conflicts, and ensuring alliance partners contribute fairly. Supporting Israel and combating antisemitism are also crucial elements of this policy.

Fleitz argued that backing Israel transcends mere sentimentality, saying, “Supporting Israel aligns with our strategic interests.” He emphasized that Israel faces regional adversaries that the United States might otherwise confront directly, making the alliance beneficial for U.S. strategic goals.

Israel as America’s forward defense

Mike Makovsky, CEO of the Jewish Institute for National Security of America (JINSA), said Israel effectively absorbs threats that would otherwise demand U.S. military action. “Historically, there are about three reasons why we have interests in the region,” he said. “One is Israel. Two is oil. And three is Islamic extremism — terrorism, Shia and Sunni.”

Makovsky said it is ironic that the America First debate has resurfaced “only a few months after Israel smoked America’s Mideast enemies.” He pointed to Iran’s nuclear advances and the role of its proxies. “They’re building ballistic missiles… They could reach the eastern seaboard of the United States,” he said. “You marry missiles with nukes that could hit the U.S. — you’ve got the North Koreans on the West Coast; do you really want Iran that could hit the East Coast?”

According to Makovsky, Israel’s campaign against those threats shows the alliance’s strategic value. “What did the Israelis just do? They took care of it. The United States came in with the B-2 at the very end… but it was Israel that did all that work,” he said.

He added that Israel “pretty much finished off Hamas,” weakened Hezbollah — “which has hundreds of American soldiers’ blood on their hands” — and continues to confront the Houthis to “ensure freedom of navigation.” That, he argued, is deterrence in action: “As long as we support Israel, we give them some help, we give them the weapons they need, they’re really doing our work.”

Countering Iran and its allies

Fleitz called Iran “the biggest threat,” encompassing “Iran and Iran’s proxies in the region. This includes Hamas, Hezbollah in Syria, Iran-backed militias in Iraq, and then Iran itself, with its nuclear weapons program and its sponsorship of terror.”

He said Israel’s actions have “destroyed Hamas proxies and significantly weakened Iran,” adding that “we joined Israel in June in taking on Iran’s nuclear program, which was a threat to global security.”

Both analysts framed Iran as part of a wider axis of power alongside Russia and China, each exploiting Middle East instability to undermine U.S. influence — by fueling proxy wars, spiking energy prices, and threatening trade routes through the Gulf and the Red Sea. Fleitz said Trump’s willingness to act decisively “to attack Iran’s nuclear program” exemplified using strength to prevent costlier wars later.

Energy and economic security

Both agree that energy policy is where America First becomes measurable. Fleitz said that “energy independence is a very important part of President Trump’s America First policy to free Americans from high energy bills.” At the same time, he noted, energy diplomacy abroad reinforces economic security at home. “By pushing the Saudis — and the Saudis, I think, are happy to help us with this — to produce more oil, it may actually help us end the war in Ukraine,” he said.

Makovsky made a similar case for regional stability: “The biggest threat to the Gulf Arab oil exporters … is Iran,” he said. Without Israel’s containment of Tehran, “Iran would have taken over the Middle East, most likely. And if you care about oil prices, that’s not too good.”

Both experts said that when Israel shoulders the burden of defending energy corridors and trade routes, Americans save in both dollars and deployments.

Avoiding unnecessary wars

Fleitz said Trump’s doctrine is about selective force, not retreat. “He wants to keep our country out of new and unnecessary wars, but he will use military force prudently to defend our national security,” he said. “He is going to avoid sending American troops into certain situations and using military force. But that doesn’t mean he won’t do these things when it is in U.S. strategic interests.”

He pointed out U.S. personnel who are currently stationed in Israel but “they’re not going to Gaza” and “will not be engaging in combat operations against Hamas.” Their mission, he said, fits the model of minimal footprint, maximum leverage.

Credibility and global deterrence

Makovsky warned that abandoning Israel would erode America’s credibility worldwide. He recalled what a senior Arab leader once told him: “If America doesn’t help Israel attack the nuclear facilities of Iran, it will be one of the great catastrophes.”

“That’s because everybody in the Mideast, everyone in Asia, knows that the U.S.–Israel relationship is one of the closest in the world,” Makovsky said. “If we don’t help Israel, it undercuts our credibility. The Chinese and the Russians and the North Koreans know that if we’re not going to support Israel, we’re not going to help other allies … and it would make us more vulnerable to the Chinese without a doubt.”

Peace through strength

Fleitz said Trump’s “20-point peace plan” for Gaza exemplifies the America First balance between toughness and diplomacy. “It achieved its two primary objectives, getting all the living hostages out of Israel and enacting a ceasefire,” he said, acknowledging that “the ceasefire is fairly shaky.” The next step, he added, is “an international stabilization force” — a complex process still under negotiation.

For both experts, the takeaway is the same: America First doesn’t mean isolation. It means strategic partnerships that keep U.S. troops out of long wars while preserving American dominance.
