Arnold is no longer a cleared DoD employee, and he is now writing a military spy thriller novel. Arnold is including information and events in his book that he has experienced throughout his DoD career. Does Arnold have to submit his book for a prepublication review before submitting his book for publication?

Yes, Arnold needs to submit his book for pre-publication review before publication. This is because, before he started working for DoD, he must have signed some Non-Disclosure agreements not to discuss some informations or technologies which he came across in the organization.

The pre-publication review would help to ensure that, there is no sensitive information about DoD which he put in his book for public consumption.
