Lets start here, when did Serbia attack Slovenia? I would really like to know.
1991 (called the 10 days war) serbian troops did attack slowenia (they made it till the Austrian border “You know Austria borders slowenia). Bevore they have been “driven” back.
But ok i guess in your oppinion maybe this is a lie too.
I guess Austria deployed 10.000 soldiers (and killed 2 serbian soldiers because they once returned fire when some of their artillery shells started to impact a few meters on “our” side of the border) on the slowenian border just for fun.
