Diluted IPv4 is one thing. Hijacking space allocated to another entity
is another. As long as they keep it contained within their network,
it's pretty much up to them to break their own environment however
they see fit, but, if they start leaking 7.0.0.0/8 or subset announcements
on to the internet in general, I wouldn't want to be them or one of the
companies that was accepting their routes.

I don't think they have to hijack space from DoD. I think there are a
number of other options available to them. They might cost more, but,
they also come with somewhat lower risks.
