In a development that has reverberated through foreign policy and intelligence communities in Washington, U.S. defense officials have reportedly raised the counterintelligence threat level posed by Israel to its highest possible designation, amid concerns that Israeli intelligence agencies may have stepped up efforts to monitor and gather sensitive information from American officials involved in diplomatic and policy deliberations related to Iran. According to reporting by NBC News and other outlets citing current and former U.S. officials, the Pentagon’s Defense Intelligence Agency (DIA) issued a revised assessment in recent weeks, upgrading the threat from “high” to “critical” within internal U.S. counterintelligence classifications.

Officials familiar with the matter, who spoke on condition of anonymity due to the sensitivity of the intelligence, told NBC that the DIA’s internal message, viewed by at least one current official, asserts that Israel’s “ability to conduct human espionage and technical collection is at a critical level.” The assessment reportedly includes a seven?page document detailing a series of incidents that heightened concern, although the officials did not point to a single triggering event. The concerns center largely on alleged efforts by Israeli intelligence services to penetrate or monitor internal U.S. deliberations on Middle East policy, particularly ongoing peace talks with Iran meant to end months of conflict that began with U.S. and Israeli strikes in late February.

According to the reports, Israel’s alleged surveillance activities have centered on senior American officials, including President Donald Trump’s top envoy for Iran negotiations, senior Pentagon policy officials such as Elbridge A. Colby, and one of his deputies, Michael P. DiMino IV. Instances of anomalous software detected on the personal communications devices of U.S. defense personnel while in Israel were cited by some officials as indicative of aggressive intelligence efforts. Analysts note that intelligence gathering — even between allies — is a longstanding practice, but officials said that the scale and focus of the alleged activities were beyond what is typically expected.

The intelligence finding comes at a delicate moment in efforts to broker a ceasefire and potential de?escalation with Iran. Tehran announced last week that it was halting indirect message exchanges with Washington, citing Israeli military operations in Lebanon and continued regional hostilities, a move that risks derailing the already fragile diplomatic process. Reuters reported that Iran could also threaten strategic chokepoints such as the Strait of Hormuz if tensions escalate further. These regional dynamics underscore the broader geopolitical stakes for U.S. policymakers and highlight the potential for alliances to be tested amid conflicting strategic objectives.

Despite the internal Pentagon assessment, the charges have been publicly contested by the White House and Israel. A spokesperson for the Israeli Embassy in Washington stated that allegations of espionage against American officials are “completely false,” asserting that Israel directs its intelligence operations at adversaries, not allied governments or their personnel. Similarly, a White House official, speaking on the record to NBC News, described the reporting as false and sourced to individuals “who don’t have any knowledge of what’s going on.” The Pentagon itself has declined to comment publicly on the intelligence assessment.

The alleged espionage concerns have prompted a broader debate in Washington over the nature of intelligence relationships with allies. Historically, the United States and Israel have maintained deep security cooperation and intelligence sharing, particularly on issues related to counterterrorism and regional threats such as Iran’s nuclear program and Hezbollah. However, concerns about espionage between allies are not unprecedented; the most notorious past case remains that of Jonathan Pollard, a U.S. Navy intelligence analyst who in the 1980s was convicted of passing classified information to Israel and sentenced to decades in prison.

Intelligence experts caution that while allies occasionally spy on one another, heightened counterintelligence alerts during sensitive negotiations can disrupt trust and collaboration. Emily Harding, vice president for defense and security at the Center for Strategic and International Studies in Washington, told NBC that Israeli intelligence agencies are known for their assertive collection efforts and keen interest in U.S. strategic decisions. Enhanced counterintelligence measures — such as increased use of secure communication devices by U.S. officials when traveling abroad — are likely to be adopted in response to the reported threat elevation.

Lawmakers on Capitol Hill have reacted with concern, with some calling for hearings to examine the implications of the intelligence assessment for U.S. national security and foreign policy. Critics argue that the disclosures could undermine trust between Washington and Jerusalem at a time when coordination is critical to addressing shared threats in the Middle East. Others contend that the Pentagon’s internal assessment reflects standard vigilance rather than a rupture in bilateral relations.

Amid conflicting accounts and official denials, U.S. and Israeli officials have indicated that day?to?day intelligence sharing remains intact, particularly on operational matters related to the Iran conflict. Nevertheless, the episode has raised important questions about the intersection of intelligence activities, diplomatic negotiations, and alliance management. With peace talks still tenuous and regional tensions simmering, how Washington and Jerusalem address these counterintelligence concerns may influence broader policy coordination in the months ahead.
