lol by 2050 their population is projected to go under a million, and they are all spread out over Northern Epirus so wiping them out piecemeal would be fucking easy especially with modern radiological weapons. Spray an isotope with a few days half life, it takes out all their country, and in six months it's a pure nature, not a single animal with body weight above 10kg exists in it.
Populate it with some Pudus, plant giant trees, and return the Balkan Temperate Rainforest to its glory days.
For right now, until 2050, focus on fucking as many serb girls as you can. Go after teens, go after milfs, impregnate the shit out of them, they are all lonely anyway it will be good for them to have a kid to take care of. Distribute condoms with bottles of baby oil as lubricant baby oil decomposes latex.
EU a shit, Greater European Co-Prosperity Sphere for ever. Maybe the real imperialism wasn't the land or subjugation, but the friends we made along the way
