ISLAMABAD: Amid rising fears of a broader Middle East conflagration, retired US Army Colonel Douglas Macgregor has warned that Israel could resort to nuclear weapons if facing defeat in its ongoing conflicts, a scenario that could reshape global security dynamics.
This stark assessment comes as tensions between Israel and Iran intensify, with recent Israeli strikes on Iranian targets prompting retaliatory threats.
Macgregor, a decorated combat veteran and former advisor to the US Secretary of Defense, emphasized in recent interviews that Israel’s perceived existential threats might push it toward extreme measures.
In a February 2026 statement on X, Macgregor highlighted Iran’s vast missile arsenal compared to Israel’s resources, questioning if desperation could lead to nuclear escalation.
He noted that Iran possesses “almost limitless assets” relative to Israel’s capabilities, underscoring the asymmetry in a prolonged war of attrition.
Historical context reveals Israel’s undeclared nuclear arsenal, estimated by experts at over 300 warheads, deployable via land, air, or sea platforms.
This monopoly has long deterred regional adversaries, but Macgregor argues that Iran’s advancing missile technology and proxy networks challenge this dominance.
Data from the Stockholm International Peace Research Institute indicates Israel maintains ambiguity over its nuclear program, refusing to sign the Nuclear Non-Proliferation Treaty.
In contrast, Iran has enriched uranium to near-weapons-grade levels, with the International Atomic Energy Agency reporting stockpiles sufficient for several bombs if weaponized.
Macgregor, in a September 2025 X thread, discussed Pakistan’s nuclear umbrella extending to Saudi Arabia, complicating any Israeli preemptive action against Iran.
He pointed out that China’s arms exports to Pakistan, exceeding 60 percent of its total between 2020 and 2024, bolster this alliance.
Such developments, Macgregor warns, make nuclear calculations “exponentially more dangerous” for Israel.
US involvement adds layers of complexity, with Macgregor criticizing Washington’s unconditional support for Israel as enabling potential mass destruction.
In an April 2025 X post, he stated that no regional power can possess nuclear weapons without threatening Israel’s supremacy.
This echoes broader geopolitical shifts, where US arms transfers to Israel, totaling over $6 billion in recent aid packages, fuel escalation risks.
Macgregor has repeatedly argued that attacks on Iran’s nuclear facilities remain a longstanding Israeli goal, potentially triggering Russian intervention.
Moscow’s alliances with Tehran, including arms supplies and joint military exercises, could internationalize the conflict.
A 2024 LifeSiteNews interview with Macgregor predicted that an Israeli assault on Hezbollah might involve tactical nuclear weapons due to dense defenses and missile threats.
He described such weapons as “the most appealing option” for Israel against fortified positions.
Tactical nukes, with yields equivalent to 10 kilotons, mirror the destructive power of massive ordnance air blasts like the US MOAB bomb.
Macgregor, in a February 2025 X post, equated supplying MOABs to Israel with incriminating Americans in mass murder, potentially uniting Islamic states against the West.
This could lead to a “path to Armageddon,” as he phrased it, with global powers aiding adversaries.
Iran’s restraint, according to Macgregor in an Instagram reel analysis, stems from avoiding war despite capabilities to “wipe out Israel in 24 hours.”
He claims the US and Israel, not Iran, are pushing toward conflict, inverting common narratives.
Data from the Arms Control Association shows Iran’s ballistic missiles, with ranges up to 2,000 kilometers, can target Israel effectively.
Recent exchanges, including Iran’s April 2024 drone and missile barrage following an Israeli strike on its consulate, demonstrate this reach.
Israel’s Iron Dome intercepted most, but vulnerabilities persist against saturation attacks.
Macgregor warns that prolonged attrition favors Iran, with its proxies like Hezbollah possessing over 150,000 rockets per US intelligence estimates.
Hezbollah’s arsenal, enhanced by Iranian technology, could overwhelm Israeli defenses in a full-scale war.
In a YouTube discussion titled “Iran Will Win & Israel May Not Survive,” Macgregor argued that Western hegemony in the Middle East is ending.
He predicted strategic failure for the US and Israel, with Iran emerging stronger.
This aligns with his view that US policymakers underestimate war’s costs, leading to unrealistic demands on Iran, such as dismantling its missile program.
Such terms, he says, amount to surrendering sovereignty, making diplomacy a facade for predetermined conflict.
Nuclear thresholds lower in desperation, Macgregor cautions, granting license to other nations if Israel deploys such weapons.
He referenced potential spread to Hezbollah, widening the war with “ominous implications” for Israel’s existence.
Economic fallout looms large, with Middle East conflicts disrupting global oil supplies.
The Strait of Hormuz, through which 20 percent of world oil passes, could close in escalation, spiking prices per International Energy Agency projections.
Refugee flows, already straining Europe from Gaza and Lebanon displacements, would surge.
Macgregor urges de-escalation, advocating for nuclear-free relations with Iran, but notes Israel’s opposition as a “stickler.”
Washington’s grip under Israeli influence, he claims in interviews, prioritizes foreign interests over American security.
Critics like Macgregor see this as jeopardizing the US Constitution and inviting war to American soil.
As of March 2026, no direct nuclear threats have materialized, but simmering proxy wars keep the powder keg lit.
Iran’s uranium enrichment at 60 percent purity, per IAEA reports, nears the 90 percent weapons threshold.
Israel’s undeclared status avoids scrutiny, but Macgregor insists transparency is key to stability.
His warnings resonate amid Trump’s administration policies, which Macgregor slams for unprovoked attacks on Iran.
Ultimately, Macgregor’s analysis paints a grim picture: defeat could drive Israel to nuclear extremes, unraveling regional and global order.
Policymakers must heed such voices to avert catastrophe, prioritizing diplomacy over dominance.
