Croats, Bosniaks, Serbs and Montenegrins all constitute a singular Nation. This is one thing Tito got dead wrong. Serbo-Croat is a term mainly used in linguistics because it's literally the same language and language is the primary basis of Nationhood.

Genetic testing has also shown that these four groups have an identical genetic origin, which simply compounds the basis of singular Nationhood. This Nation does not include Slovenia as their language is not mutually intelligible (and no, obscure dialects with some differing words does not constitute a separate language).

Having a different religion or language script is also not the basis of Nationhood. The Albanians themselves showed this with the late 18th Century Romantic Nationalist movement exemplified by the poetry of Ember Pasha. The Albanians, in contrast, has a completely different genetic origin and Albanian is it's own branch of the Indo-European languages. This is why 95% of Kosovo belongs to Albania.
