You can be technically 'right' by some definition and an intervention still not being a good thing. The Southern regime was incredibly corrupt and dominated by land owners. Look at the Philippines for an example of what happens to a US 'colony' where the land lords are in control. Communist Vietnam did some bad reforms yes, but they also changed and eventually did a lot of good things, turning the country into what it is today. The US spent decades of war propping up a regime that was mostly incapable and killed a lot of people in the meantime.
