An interesting footnote to WWII.  A couple of observations: 
1.  In reality, there were no German plans for the U.S., although I think there may have been vague wish lists for colonies in the Caribbean - but this was little more than thinking out loud by top nazis in dinner conversations.  Of course, who knows what might have happened later on, (say, the late 50's), if the unthinkable occurred and there was a German conquest of Britain and Russia by the mid-40's.
2.  It's interesting that the author of these scenarios can't bring himself to suggest that Britain would have to be conquered before Germany took on a North American campaign - nice sentiment, but almost hallucinatory in terms of realism.
3.  I am of two minds on the Japanese scenarios presented.  The first is the now traditional view that Japan's plan was to basically conquer a lot, fast, (including Hawaii), heavily harass the West Coast of the U.S. and then wait for us to either sue for peace, or let us wear ourselves out in a brutal war of attrition as we tried to reconquer the Pacific - and then we were expected to sue for peace.  But I seem to remember somewhere back in my innocent youth reading about a Japanese strategist who came up with the original plan for WWII - and it DID include an invasion of California (!).  But at this point I can't vouch for the veracity of it, nor if it might have gained official recognition in the High Command as an ultimate goal.  I would add that such a scenario would be a logistical nightmare for the Japanese, and I've never seen any evidence to support the industrial power they'd have to have to conduct such an operation.  As it was, they were barely holding on by late '42, and it was all downhill after that, economically and logistically speaking.
