One way or another, the KGB gained information from the Israelis we didn't want them to have. This is why we don't simply share everything willy-nilly with allies - you have no way of knowing where it goes after it leaves your hands.

As others have noticed, the Israelis have different priorities than the US. If trading our info to our enemies results in them saving some of their people's lives, at the cost of some of our people, we cannot count on them to be altruistic about it.

The bottom line is they value their people more than ours, and they value their security and interests more than the US's. In many things we have divergent and competing interests

As they should. And we should, of course, value our people more than theirs - with that in mind, they don't (and shouldn't) get the keys to all the files. This is simple common sense, it seems to me.
