Let's postulate that Reconstruction is successful to a standard of "the 13th-15th amendments are vigorously enforced, the rights of African-Americans are preserved, esp. wrt voting, and either the bans on segregation in public accommodations are upheld (1875 Civil Rights Act) or at a bare minimum legally enforced segregation in public accommodations is held to be unconstitutional"-ie. there's no actual Jim Crow regime or post-1880 nadir even if we're stuck with some level of informal de facto discrimination. I'm fine with any means to this goal post-1865. My question is: What are the foreign policy consequences of this? What does the foreign policy of a post-1877 US under this circumstance look like, and is it noticeably different from the foreign policy of OTL's US?
