Kidnapping people to face punishment without fair trial seems wrong no matter who does it.
Kidnapping is only one of the ways we ingest people to treat in this manner, if I recall right. Presumably one could be arrested and then renditioned elsewhere -- the rendition is the part where we send someone elsewhere to be harmed in ways that our laws don't permit us to do ourselves.
Same with terrorism - it’s evil, unless it’s Blackwater.
Extraordinary rendition is one of those things the world has settled on as being unlawful.
The actual answer is: when geopolitical allies do distasteful things we use euphamisms, when geopolitical enemies do it, we drop the propaganda pretense.
> an important distinction as compared to simply violating some foreign country's laws to bring someone to (your idea of) justice
Is the important distinction you want to make that its only wrong if your violated a different country's laws and not your own (personally i'd view that as worse)? Otherwise i struggle to see what the distinction you're trying to point out here is.

Though, I think it should also be a crime for the US to plot the kidnapping or assassination of foreign dissidents too.
