Thank you very much for your help! Of neutral powers, I would like to ask about what will the general to create for them the army, about how to know their status, I know. After all, Switzerland, Holland and China have the army, although they may come into war only if they are forced to enter there, that is, to declare war on them (although in reality, China has participated in the war, knowing this, I tried to lure him to the side of the Central Powers in opposed to Japan, but he only took in a pro-central powers position and all, probably an effect rule out that China will never join on the side of the Central Powers). I just also wanted to say that it would be realistic that the neutral Powers also have the army, because in reality, Sweden is pro-central position, and the Russian intelligence actively watched her in years 1914-15, since it can enter into War for the Central Powers.
I'm sorry I wrote it in Spanish forum, I just did not understand that this is a purely Spanish forum, in the future it will not happen again.
