Leaked documents reveal US sees Israel as a spying threat

By Julian Pecquet - 08/29/13

The Obama administration views Israel as one of the top spying threats facing its intelligence services, leaked documents reveal.
A secret budget request obtained by The Washington Post from former NSA contractor Edward Snowden lumps Israel alongside U.S. foes Iran and Cuba as “key targets” for U.S. counterintelligence efforts. The document suggests Israel does not believe U.S. assurances that its interests are aligned with Israel's on crucial issues such as Iran and peace talks with the Palestinians.
