In this case you probally should have made a new thread. Only bump if you've something major to add to the existing topic, not a new, similar question.
Though its not a big deal, people only get in trouble for persistant and stupid necroing.
The trouble with Hawaii was that though it was modernising in a 'meiji' kind of way all of the foreign investment was coming from the US. In Japan's true meiji meanwhile they had a pretty good balance of lots of foreign interests.
Also a problem for Hawaii is it was small. Pretty easy for a few rich foreigners to end up owning huge chunks of the country.
So for Hawaii...you need better laws about foreign land/business ownership that can balance still getting investment without them buying the country, and get the US less interested and some other powers more interested. Maybe have Mexico keeping California et al and becoming a real rival to the US.
