What methods did the us government use to annex new lands?

The United States of America pursued a fairly active colonial policy, expanding its expansion in the Atlantic and Pacific Ocean. In fact, the methods used to conduct such policies were often dishonest. For example, Hawaii was subordinated in the following way – American immigrants staged a coup there and after that a puppet state was formed there, which was directly subordinate to the United States, and then Hawaii was annexed and included in its composition. The method of direct armed seizure of certain territories and lands was also used.
