The WW II CROs used to tell their Nazi dinner guests that Croats are really not Slavs, but Goths. And Slovenes are “alpski Hrvati” Alpine Croats. And Asterix was Tudjman’s great-grat grandfather.
BTW, read the Catholic Encyclopedia (it’s on line), in the article “Albania”. There you’ll find that Holy Mother Church writes about “the westernmost Serbs, who are called HROATS”...
The Ustashe got the Goth part wrong, similar to Serbs who claim how their ancient empire stretched all the way to the Volga.
