The Wikileaks people are pretty sharp. I’m fairly confident they have this information backed up and ready to roll out from multiple places. I’m fairly confident that trying to shut them down would be like cutting one head off the hydra : two more grow back.
I agree with you, though, that they might decide to do one massive dump to get it all out. I wonder what their game plan is and why the drip, drip, drip. Is what they release at any given time a strategic decision? Or are they checking them for things that really might endanger innocent people and releasing them after they’ve passed inspection? Is there some sort of end game?
