Yeah, I miss those days. It was a simpler time back then for me, but time goes on and I just have to get used to it.
Well, for those types of situations, both roleplaying parties or nations will have to agree to that scenario. That way, a nation can't just make up a rping event to drag you into a war. Which means nation rping won't be as crazy as you think it will be. On the other hand, we can also roleplay as people in a particular nation or scenario, which won't have as monumental of an impact as rping as a country.
