Why has the Pentagon raised the risk of Israeli spying to the highest level?

The US defence department has reportedly raised its assessment of the espionage threat posed by Israel to the highest category of “critical”, according to media reports citing American intelligence and defence officials.

The assessment, first published by NBC News on Friday and followed by The New York Times, comes at a time when Washington is pursuing diplomatic engagement with Iran, while its ally Israel is opposed to the talks aimed at ending the conflict now 100 days long on Sunday.

US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu have publicly diverged in their approach to the war – Washington wants to extricate itself amid political pressure, while Israel is still pushing to topple the Iranian government.

This is not the first time Israel has been accused of espionage against the US – its closest ally and benefactor – with which it maintains extensive security and intelligence cooperation.

According to NBC News and The New York Times (NYT), citing anonymous current and former US officials, the Pentagon’s Defense Intelligence Agency (DIA) arm recently upgraded Israel’s counterintelligence threat level from “high” to “critical”, the most serious designation in its internal assessment system.

The warning was based on Israeli intelligence agencies intensifying efforts to collect information on US military personnel, government officials and policy discussions.

The news reports said the concern was focused on American officials involved in shaping Washington’s approach towards Iran, as the two foes continue to negotiate an end to the war that has sent global energy prices soaring.

“An intensified Israeli effort to learn about US positions in talks with Iran has crossed a line, according to some American officials,” the NYT said.
