American business interests needed to be protected
Explanation:
The intervention of the United States in Nicaragua was mostly because of economic interests. The us wanted to have full control of the small Central American nation as it was located in a place that had the potential to be both of great benefit for the United States, but also to create a lot fo economic damage. One of those economic reasons was the planned canal in Nicaragua, that was going to compete with the one in Panama. Having the Panama canal under their control, the US didn't wanted another one that was going to compete with it and take away large portion of the money that they had secured with it.
It is a huge thing but main reasons for pushing were victory and economic opportunity because the U.S. was in an economic depression war was what we needed to regain economic stability
