Since I first heard about FVEY, I have assumed that each of the member countries has total unrestricted access to 100% of the data that any of the other member countries have collected.
The more that we find out, the more I believe that that is an accurate assumption.
You are probably right. Given the MOU with Israel, there are restrictions certainly for other governments.
Those restrictions include, presumably, that they agree that among eachother they promise not to read achothers' emails, and furthermore if they do this and use the information to spy on our government, they promise to do so discretely....
