It is amazing just how much Israel spies on America, and how nobody knows about it. If you dare to say it publicly then your reputation and career are destroyed, and you are an antisemitic terrorist sympathizer, if not also a terrorist.
Spying, tapping, hacking, etc are not acts of war. In fact, they probably prevent more conflict than they could possibly ever cause.
Had we listened to Israeli spies, we would have never gone to war with Iraq over WMDs. Spies save lives.
It's amazing how HNs usual standards of logical discourse seem to disappear once the argument becomes political.
It is you who have claimed that "nobody knows about it", and therefore it's neither obvious nor extensively written about, and it is you who holds the burden of proof.
