Looks good, a lot of detail on the history section. That's a good thing, but it's also fine if someone wants to give less when making their application. I wouldn't count distrustful of other nations as a disadvantage, as it's more about how the nation approaches diplomacy rather than a feature of their society. If that distrust was strong enough that they reject the influence of other nations even when doing so makes modernization and development harder, you could take Entrenched Traditions. As is it's accepted, and you can post it in the characters tab. As of your bio, I guess there was a first world war in this world also, but I'll leave the details of what happened in it up to whoever wants to fill them in. 

Bing, that's a good idea but I'm not sure how I want to handle it. I'll make an edit to the OP soon with something to address that.
