I read it. Loftus either does not understand how intelligence operations work, or he's deliberately shutting his eyes to an embarrassing truth.
Pollard passed over much information provided by those spies, which then made its way to the USSR. That information greatly facilitated KGB investigations. Match the list of spies with the bigot lists for the information Pollard passed, and you've just confirmed that Ames wasn't passing BS.
Pollard and Ames should be sharing a cell on death row.
You go on ahead pretending that Pollard didn't get thos agents shot, and I'll just go on considering you someone who places the national security of Israel ahead of the national security of the United States.
