What is the problem with a short battle without any ending terms?:
None.(Unless on the receiving end, then feel free to QQ)
What is the problem with alliances starting an aggressive war?:
None, it keeps Planet Bob moving. Intellectually, debates start. Artistically, war propaganda is made. In the end some are satisfied, some aren't. Either way, you weren't bored to death.
Why do you wish for a world of peace, a world without war?:
I don't. Drama is excellence. Peace is war. War is Peace. War fuels passion. Passion fuels creativity.
How did I do?
