a policy of expanding a countries boundaries
The term for expanding territory is "territorial expansion" or "imperialism." It refers to the process of a country acquiring new land or territories to increase its size and influence.
The two rivers that partially form the eastern boundary of the United States are the Mississippi River and the St. Lawrence River. The Mississippi River flows southward from Minnesota to the Gulf of Mexico, serving as a significant boundary for several states. The St. Lawrence River, situated in the northeastern part of the country, forms part of the boundary between the United States and Canada.
A policy of expanding a nation's boundaries is called imperialism. This involves a country extending its power and influence through military force, diplomacy, or economic means to control territories beyond its borders.

Expansionism is a process of a country expanding its economic influence, not necessarily by military means. Imperialism extends the countries power by colonisation with the use of military force
