Allow me to respond here. First, I will explain the current setup of governments in the Balkans based on gameplay issues. As things were in v0.5 and most other mods, Balkans was full of Paternal Autocrat governments. This made them very easy to influence through diplomacy by Axis powers. Essentially, Hungary, Romania, Yugoslavia, and Bulgaria almost always ended up in Axis, and Greece and Turkey joined about half the time. This is both ahistorical and messes up the gameplay by allowing Germany to concentrate on Soviet Union without a fight in the Balkans and allowing Italy to concentrate their entire army in North Africa. Our previous experiences have shown that this leads to a quick collapse of British and French North Africa and a very ahistorical game. Also, the reduced distraction for Germany makes her very formidable against the USSR. Basically, Germany gets PA governments into her camp far too easily, especially since historically their Axis allies were reluctant at best.
To resolve these problems, we changed government types in Balkan countries to match their historical lineup. Mostly, Yugoslavia is still PA but it cannot be diplomatically added to Axis alliance. A set of events was made that prevents this, and this set is based on very strong historical facts. Another set of events allows Germany to pressure Yugoslavia into submission after fall of France, but even in this set the chance of a successful diplomatic alliance between Yugoslavia and Germany is miniscule (less then one percent). War is a far more likely outcome, as history showed.
Greece is another issue. Frankly, Paradox made a mistake in making it PA. While it could be argued that it's Metaxas government was not very democratic, it was strongly leaning towards Allies and against Italian territorial ambitions. Of course, in HoI any PA government is more then likely to join Axis. Therefore, to reduce this ahistorical outcome, we changed the type of government to a more democratic one. When tied with Italian DoW on Greece events, this has the added benefit ot tying up a large portion of Italian army in Greece, where they bog down most of the time. This is a very desirable historical outcome, and it also helps the British in North Africa.
As far as DoW-ing Yugoslavia and Greece, this is handled by a chain of events describing the Balkan campaign in spring of 1941. Generally speaking, if game sticks closely to history in early war (Poland falls, France falls), the German player will get a choice to try and to pursue a Balkan campaign through threatening Yugoslavia. Following this chain with default choices will give you a free, no-dissent-hit DoWs on both Yugoslavia and Greece. In fact, the DoW on Yugoslavia will even reduce your dissent a little if Yugoslav side plays it correctly. If, however, this is not enough for you, and you want to indulge yourself in gobbling Hungary, Romania, Bulgaria, and Turkey, you will just have to pay the dissent penalty...
