USA almost certainly spies on Israel (and everyone else) far deeper than anyone spies on them.
Do you have an example?
Or when you said “they sure do” did you mean “they possibly do,” since no example is available but you can’t rule it out?
John Kiriakou [1] will spend 3 hours talking about the CIA's torture program (illegal) and NSA spying on Americans (illegal). In the same conversation, he will insist that the US would never spy on Israel because it is illegal.
Who is this fooling ?
[1] Senior ex-CIA official, whistleblower & internet meme phenomenon.
But no one without at least a TS really knows
I think at most we get a indirect "confession" like Andrew Bustamante gave in some podcasts like here, where he answers to the question if the US spies on the Mossad that everybody spies on everybody and than distract to the case were the US was caught spying on (it's ally) Germany: https://www.youtube.com/watch?v=mZklvHVsaT4
PS: I guess at the end you didn't spy until you were caught spying.
And it sounds like you are setting up an untestable claim. Can’t help you there. Believe what you want.
Guess what happens anyways?
That said, he probably isn't wrong at all about this particular thing.
In this case the writing part is not important.
