The Islamic Republic of Iran significantly escalated its war effort against the U.S. with its launch of two intermediate-range ballistic missiles on Friday toward Diego Garcia, a key U.S.-U.K. military base in the Indian Ocean.

The targeting of Diego Garcia, roughly 2,500 miles from Iran, means Tehran’s missile capabilities appear to have exceeded previously acknowledged limits.

In the period leading up to Operation Epic Fury Feb. 28, Iran Foreign Minister Abbas Araghchi claimed, “We intentionally kept the range of our missiles below 2,000 kilometers so we don’t have that capability. And we don’t want to do that because we do not have hostility against the United States people and all Europeans.”

On Saturday, Israel Defense Forces Chief of Staff Lt. Gen. Eyal Zamir said, “Just yesterday, Iran launched a two-stage intercontinental ballistic missile with a range of 4,000 kilometers [2,500 miles] toward an American target on the island of Diego Garcia. These missiles were not intended to hit Israel. Their range reaches the capitals of Europe — Berlin, Paris and Rome are all within direct threat range.”

IDF spokesman Nadav Shoshani blasted the alleged Iranian deception on X, writing, “Just 3 days before the war, the Iranian regime said they don’t obtain long-range missiles. Today, their lies were exposed once again, when missiles were fired 4000km away from Iran. They hoped to lie their way into becoming a force that can terrorize the world. We didn’t buy it.”

Jason Brodsky, the policy director of United Against Nuclear Iran (UANI), told Fox News Digital, “The Trump administration, in citing Iran’s missile threat as a rationale for Operation Epic Fury, was therefore justified in its decision to undertake military action as Iran has consistently refused to negotiate over its missile program.

“It also shows how dangerous it is to solely rely on Iranian nuclear weapons fatwas and the supreme leader’s public rhetoric in formulating U.S. policy. As long as Iran retains the technical capability beyond public pronouncements, it is a threat.”

“I think it’s a message that the IRGC is in charge in Iran after Supreme Leader Ali Khamenei’s death,” Brodsky said. “When Khamenei was alive, he limited the range of Iran’s missile program to 2,000 kilometers. Khamenei recounted in 2018 how he had rejected overtures from IRGC commanders seeking to increase the range to as much as 5,000 kilometers.

“But now that he has died, those voices in the IRGC seeking to increase the range are likely driving the agenda. The launch of the missiles was likely meant as a signal of the IRGC’s capabilities to threaten U.S. allies beyond the Middle East. For example, this threatens Europe.”

The two long-range Iranian missiles did not hit the base, but the attempted attack marked a significant expansion of Iran’s reach beyond the Middle East and toward a major U.S. strategic hub. One missile reportedly failed in flight, while a U.S. warship launched an SM-3 interceptor at the other, officials said. It was not immediately clear whether the interception was successful. The remote base is a critical launch point for U.S. bombers, nuclear submarines and other strategic assets.

Ilan Berman, vice president of the American Foreign Policy Council in Washington, D.C., told Fox News Digital, “The launch hammers home the president’s point about Iran being an imminent threat. It’s easy for casual observers to ignore, but the increasing maturity of Iran’s strategic programs, plural, has been exponentially expanding the threat that the Islamic Republic poses beyond the Middle East. 

“That is what Epic Fury is seeking to address. The administration believes, absolutely correctly in my view, that these types of capabilities cannot be left in the hands of a radical, predatory regime.

“Despite its public denials, it’s been clear that the Iranian regime has been working on expanding the range of its ballistic missile capabilities for years. The launch toward Diego Garcia confirms that it has made real progress toward that goal and is already able to put targets in the same range as Central and Eastern Europe at risk. Moreover, it’s clear that the regime is seeking still greater capabilities and that, if left intact, Iran’s ballistic missiles would attain intercontinental range soon.”

Berman, the author of “Iran’s Deadly Ambition: The Islamic Republic’s Quest for Global Power,” added, “The parallel development Iran has been carrying out on its space program is significant. The booster used to put payloads into orbit can be married onto a medium-range missile to create intercontinental range capabilities. Before the war, we were seeing a clear convergence of the regime’s strategic programs: its ballistic missile work, its space capabilities and its nuclear program.”

He warned about the serious Iranian threat to continental Europe. 

“Europe is absolutely at risk as the recent launch makes clear,” Berman said. “I wouldn’t say that a failure to recognize this to date has been due to a grand deception by Tehran, though. It is more attributable to willful blindness on the part of European elites about the extent of the threat that the Iranian regime poses as well as undue faith in diplomacy and arms control in containing it.”

On Saturday, the United Kingdom condemned the attack. 

“Iran’s reckless attacks, lashing out across the region and holding hostage the Strait of Hormuz, are a threat to British interests and British allies,” the U.K. Ministry of Defense said in a statement. “RAF jets and other U.K. military assets are continuing to defend our people and personnel in the region.

“This government has given permission to the U.S. to use British bases for specific and limited defensive operations.”
