Imperialism refers to the use of military force or otherwise to increase the influence and control a country wields on other countries. It was a very dominant policy in the 18th century amongst Western powers like Britain and France.
Queen Liliuokalani would most likely disagree with Imperialism because she lost her kingdom to it. Queen Liliuokalani was the last monarch of the independent Hawaiian Kingdom until she was deposed in a coup by mostly Americans and Europeans and then this was enforced by US Marines. Hawaii was formally annexed a couple of years afterward.
Had it not been for imperialism, Queen Liliuokalani would have remained queen so she would probably disagree with the policy.
