Recent reports suggest that Israeli intelligence agencies have been eavesdropping on American negotiators involved in discussions with Iran, raising significant concerns among US intelligence officials. The New York Times reported that Israeli efforts to gather information on Washington's negotiating stance have intensified, particularly targeting senior officials such as Steve Witkoff, Elbridge Colby, and Michael DiMino. While espionage between the two allies is not new, some US officials believe Israel's current actions have crossed a line. The Defence Intelligence Agency has elevated the counterintelligence threat posed by Israel from 'high' to 'critical', citing increased incidents of suspected spying since late 2024. Notable incidents include the discovery of surveillance software on US defense personnel's phones and past attempts to plant listening devices at US government facilities. The growing rift in strategic priorities between the US and Israel regarding Iran could further complicate military cooperation, especially if the Pentagon imposes restrictions on intelligence sharing.
