Yugoslavia in T2K

[RN7]

I'm rewriting/expanding my T2K Germany article I posted on this site last year and I'm working on the timeline section at the moment.

What is the general position that members have with Yugoslavia in T2K. My own sources from GDW are a bit contradictory.

Did Yugoslavia break up before the Twilight War or during it.

I was going to include Croatia and Slovenia breaking away and then mention the Bosnian War and NATO peacekeepers, but that wouldn't fit with T2K were Yugoslavia (Serbia) joins NATO at the end of 1996 and sends military forces to aid Romania who is being attacked by the Warsaw Pact.
