Why did the us participate in imperialism?

Answer 1

The US Frontier Wars officially ended in 1890 at the battle of Wounded Knee. The US was used to expanding, the men that had fought the "wars" needed a "reason for being" (a reason to exist), with the continent of the United States settled (in 1890), the US had to look elsewhere. That "elsewhere" was foreign adventures.

Answer 2

The word "Imperialism" as applied to the United States is a mis-nomer. The US never had such a policy. For a real-life definition of the term, and a comparison, you would have to look at the historical records of the one-time British Empire - Spanish Empire - French Empire - German Empire - Roman Empire - etc - etc. You will carefully note that they all involved invading and conquering by force and eliminating the "home-rule" of the countries they subjugated to their authority.
