USSR and the Balkans.And, as I asked earlier, what should the USSR do?
Just as the rest of USSR early war strategy everything he does should be aimed at preparing for a Barbarossa. A few key points to make.
Keep as big bufferzone on the germans as possible.
Minimise German production.
Minimise USSR losses.
Maximise USSR production.
There are two choices to make for USSR. a) Demand Bessarbia or not, b) Attack Bulgaria or not.
a.1) Demand Bessarbia
First never demand Bessarbia if you're not certain you can win a war over Rumania, count on that Germans will rail in and act as peace keepers. so keeping a cav in west poland to cut the railroad might be a good startegy.
- This will decrease your lending to Germany which will increase your production and lower his.
- It will give you Chisinau and an increased bufferzone when the attack will come.
- It will make it possible for Italy to align Yugoslavia prior to the attack of Russia, (but do you really care Italy is the wallies problem)
a.2) Don't demand Bessarbia
Only pro is really that that the germans have to attack Yugoslavia prior to attacking you to be able to align Rumania and start his assualt from Ukraine.
b1) Attack Bulgaria.
An '39 attack on Bulgaria can usually both cut off the Turkish and Bulgarian resource, even if you do not actually counquer Bulgaria, it will take a little plannign and effort but might be well worth it, a con is that when you declare war Italy might align Bulgaria and hence creating a pretty safe second home.
