"Balkans on Fire Campaign ideas...." Topic

Ok, so I'm looking to create a SF/NF campaign that involves several states in the Balkans circa 2250AD.

I'd be interested in some input as to how it starts, who gets drawn in, and who's on who's side.

I will include 3 map links a reference material. Any of the countries pictured may be included in the fray.
The only qualifiers are:

Bulgaria must be involved some way,
the US will NOT intervene,
Nato no longer exits,
Russia, Poland and Germany may intervene (Poland and Germany may be allied together but neither can ally with Russia).

Have fun, and thanks for any input!

Sides – 1. Croatia – Bosnia (federation)
2. Serbia – Bosnia (republic Srpska) – Russia

If you like take the current EU mission as your base euforbih.org/eufor This includes Poles, Germans and Bulgarians in the buffer force.

There are any number of flashpoints in BiH to get you going but you could have a number of internal border incursions with the republic being supported by Serbia or vice versa. The internationals (Pole/German/Bul) are a protective force defending the rights to a peaceful co-existence so gradually get sucked in.

All too easy to pour oil into these embers.

Bulgaria and Albania decide (with perfectly valid historical justification) to split Macedonia, between them, since the country is (according to some narrow nationalistic interpretations) composed entirely of Bulgars or Albanians anyway. [This is kinda sorta what happened in the Second Balkan War.]

Albania expands its interest to include its Kosovar brethren, at which point the Serbs intervene against the Albanians, pitting them against the Bulgarians as well (just like 1878, or was it 1868?)

Serbia's historical friend Greece, alarmed by resurgent Bulgarians and Albanians, mobilizes and allows a Russian expeditionary force into Thessaloniki (Salonika) to march north and clear the Vardar river valley north to assist Serbia. [Like 1915, or 1999, but the Russian component was a lot smaller then.]

The German-led European Union force, including Poles, in Kosovo has to fight its way out to Shkoder (Scutari in Italian) on the Adriatic coast.

There you go, Q.E.D.

Scenario One
A failure in the plum crop drive slivovitz production and supply down while prices skyrocket. A quart bottle now costs a bolt action Mauser rifle.

Scenario Two
Animal spread flues and viruses threaten humanity. The UN decides to impose a cattle blockade against importing any pigs being sold from Hungary into Serbia.

Scenario Three
Albanian tourism never develops. To inspire the local economy and also to attempt to forestall Bulgarian, Macedonian and Montenegrin plots, the locals decide to invite the Italians back.

Scenario Four
Village burning is turned down as an Olympic Event. Locals attempt to prove the vitality of the sport.

in 250 years I think geography of that region might be a tad different…….so make up whatever, Neu Byzantine Empire looking to reclaim it's land, e.t.c
