(A piece of context that's often missing from - typically charged - discussions about US/Israel relationships is the degree of dependence between the two, and how that's varied over the years. Israel's defense policies have historically been informed by a desire to be fully self-sufficient during wartime, i.e. not require active support from countries like the U.S. That policy has been deprioritized over the last 20-30 years, to the point where the US is now a significant active defense provider for Israel, rather than just an arms supplier. This is a dependency relationship that's new to the ongoing conflict, and should color any analysis of Israel's willingness to do things that would threaten its relationship with the U.S.)
I guess US gov would not like to have it be out publicly, but they must understand that this is being at least attempted and US likely does it to Israel, too.

My point here is pretty narrow: I'm sure Israel spies on the US, and we spy on them. My only doubt is whether TM SGNL itself is an element of that, or whether it's just another flavor of junk software sold to USG to paper over the gaps between technology and compliance requirements.
I mean, they stole weapons grade Uranium from United States along with nuclear secrets and we just shrugged our shoulders: https://www.theguardian.com/world/2014/jan/15/truth-israels-...
Well, guess what, it doesn't work. It's just stupid.
Israel is apparently so important to US, that US brushes away pretty much all concerns, or infractions. From Israel killing US citizens, incl. US children for no reason, stealing material for nuclear bomb from US, killing US soldiers and bombing US ships, attempting to murder US ambasador and his family/children, and making US seem like a total asshole country by it having to defend all kinds of vile actions done by its proxy in the middle east, etc.
Israel seems more like a proxy state of the US at this point.
Some minor spying would not even register. And it would be like US spying on itself anyway.
