Bulgaria joining NATO is a separate matter and all the support NATO was giving out to various rebel groups actually helped persuade any doubters of the merits of joining NATO. As they say, it's better to be a hammer than an anvil.So this is a long way before Romania and Bulgaria joined NATO in 2004, though with the NATO intervention in Macedonia, can Bulgaria choose not to seek NATO membership by this point? Bulgaria actually helped Macedonia train its army, from what I can gather. And this UCK is different from the Kosovo UCK, right?
Bulgaria did send weapons to Macedonia and the president suggested sending troops but that was shot down by the government.
It's a bit difficult to have an insurgency without any insurgents. There are far too few native Albanians left in Epirus for that. The Muslim Albanians were expelled after WWII, while the Christian Albanians have been assimilated.Also, with regards to this issue, could the Albanian insurgency against Macedonia spill over into Greece, especially with the Liberation Army of Chameria?
I'm not much of a fan of the Macedonian government but they have been pretty good in the treatment of their non-Bulgarian minorities. Not that it helped them against the Albanians...Be glad that OTL Macedonia was pragmatic and reasonable during the main phase of the 90s craziness. The insurgency issues with some UCK-supplied lunkheads in the northwest are regrettable, but it's still a lot better than having to be directly dragged into the Yugoslav Wars and endure them.
