The American expansionists were not interested in the Islands of Hawaii for the purpose to gain control of the profitable sugar industry.
Step-by-step explanation:
The Islands of Hawaii was never seen as the place for the production of sugar cane due to the isolation of the islands from the rest, so any trade that was going to take place was not going to bring in a solid amount of profit.
Instead, Hawaii was considered as a place of great strategic importance for the future, so that was the biggest reason why there was an interest of gaining control over it for a naval base and coaling stations for ships.
