it opened up future intervention in latin america.
it led to more wars with european nations.

Explanation:

The Monroe Doctrine, issued in 1823, framed the Americas as a sphere separate from European interference. While initially unenforced, it became a foundational principle that the U.S. later used to justify interventions in Latin America (such as the Roosevelt Corollary). It did not ignore the region, reduce expansionist desires, or lead to major wars with Europe.

Answer:

It opened up future intervention in Latin America.
