I think that the minister list would be (relatively) limited, actually. Most on the list would be either internationalist types or über-racial nationalist types, so most ministers would be Left-Wing Radicals, Social-Democrats, etc. but also mainly Fascists and similar types and so on, like Alparslan Türkeş. I'd assume a vast majority of ministers would be opposed to a united Turanian government.
True.
This reminds me of the question...why on Earth does the nation "England" have tons of lvl 5 generals? A bit exaggarated, hm? I could name countless German and Finnish generals with more experience and prestige than most of the aforementioned English generals combined. Also, 90% of these lvl 5 generals start with skills ranging from 2 to 4 in 1936.
For example, uniting Luxembourg, NL and Belgium into one country as one of those countries in order to create Benelux, the ability to create Austria-Hungary if Austria annexes Hungary or vice-versa, Baltic nations conquering others to create the Baltic Union, etc.
This is both a good and a bad idea. Maybe a united Low Country state might work, since the area was already at the time generally quite liberal.
In the case of Austria-Hungary...not such a good idea. Why? Well, now that all those people once under Austro-Hungarian rule had not only achieved nationalistic enlightenment, but also gotten independence, they would strongly resist renewed foreign rule. Such was the case IRL when for example Yugoslavia was conquered by the Axis. Though there are always other matters such as cultural autonomy, in-country states (for example the planned United States of Greater Austria) etc. which would relieve partisan activity, that are outside the HoI2 engine.
In the case of the United Baltic Duchy, the same rule of nationalistic partisan activity applies. But since you can liberate these countries anyway, I guess I'll just have to stop talking about nationalistic partisan activity. Anyway... Each Baltic state's event about creating the United Baltic Duchy should have a further event which would keep/move the capitol to the original country's capitol city. So as to avoid the default United Baltic Duchy capitol, which is Riga (you're going to want to avoid that if you're Estonia or Lithuania).
P.S. I was typing this around 4-5am in the morning. Just let me know if my text is somewhat incomprehensible.
