I don't understand what Bezos is thinking here. He seems to think that he can force the employees to work on military projects. What happened with Google is the employees said "it's either this project or us" and Google preferred to keep the employees. Bezos could make a different decision, but he can't keep both, and it doesn't sound like he realizes that to me.
Bezos is thinking like a manager. People are resources. If one resource quits ( beccause he/she/it does not like working for the military^W^W democracy) than he/she/it is replaced by another resource. It is that simple.
