Just like Serbs ignored Croatian, Bosnian and Slovenian interests when Yugoslavia was coming undone. Every nation thinks
Slovenians are nation. Their interests were not ignored.
Croatian and Bosnian? In majority, Serbians who were seduced by the foes, not to be Serbians. Still, even their interests were not ignored. Their sponsors wanted to use them to seduce more Serbians onto the dark side but miscalculated. Now, Croatian and Bosnian societies crumbles from within, while Catholic and Islamized Serbians want to brake free.
Every nation thinks first of all of itself, its own goals, interests and priorities.
Some nations are created to serve foreign interests, not its own. Actually, by its meaning, nation is younger then people. Nation inherit from people, due to all kind of circumstances.
So don't be surprised that Brits, Italains, French and others do likewise.
Yes, nations. Not people. They despise people from which they inherit. As you know, their ancestors were Slavs (ie Sarmatians). Meaning, among else, they would be happy only if all Poles drop dead.
