First strike information would have a limited lifespan as codes get changed over time and the mission which obtained it might be compromised in a way that the thieves might not be aware of immediately. The only reason to go after the information is because you plan to use. But the
key to that is being reasonably assured that the 'mutual destruction' retaliation could be defeated.
We are talking about the end of America here folks. That was the game in play and the Israelis obviously had a piece of the action. Somehow they assumed there would be enough of world left to make it worth the risk. Gosh, do you think the Israelis would have wanted control over all the Mid East as their cut on the deal?
Pollard was able to give them the naval submarine codes and the ability to defeat our land based missiles. Then only deterrence that we would still have had secure control over were our nuclear bombers, which of course would have been targeted in the first strike.
Are you getting the picture now why the FBI and CIA top echelons threatened Bill Clinton with mass resignations when he was within a hair of letting Pollard go to buy himself some extra retirement benefits from you know who? But they also had another reason.
Pollard has also turned over to the Israelis our entire East European agents and assets network lists that represented a generation of intelligence work to build up. Around 1100 of these people were arrested, tortured, and many of them executed. This was the intelligence failure of all human history, which no American government could admit to for the incompetence that it showed.
