Yes. It's the personal statement of a very privileged person who (like the rest of the 60s) was probably inspired to empathy with the civil rights movement triggered by the threat of the draft, but has now transferred his empathy to the more exotic minorities populating his new life of international adventure.

Now his personal feeling of threat comes more from the revolution than the state, so his opinion of revolution has changed.

Hopefully the consolation that no one will be able to download, take out from a library or buy his book without being put on a list by secret intelligence services will make him feel a little better about writing it.
