It is important to note that your question is as much a political question as it is a historical one.

First of all, there is no "kind of" intentional - it was was and is intentional. The information linked to by /u/Searocksandtrees answers your question perfectly, so I will just add a bit more information here.

The term "genocide," as coined by Raphael Lemkin in 1943, was defined by the United Nations in 1948. Under these terms, it is easy to see "genocide" being committed with the systematic removal of Indian children from their parents and placement into boarding schools; the forced removal of natives from their homelands, resulting in the well-known Trail of Tears; and even the forced sterilization of Native American women up until the 1970s.

The use of this term is further emphasized with the what the genocide convention said here and a more modern document from the UN on an analyasis framework for the prevention of genocide..

This documentary, entitled "The Canary Effect," also goes over points of genocide within history of the United States and Native Americans. It begins at around 9:00 minutes in.

It would be accurate to describe what happened to Native Americans as genocide.
