but if you are preparing for war then you have something better to do right? is it not the very same thing Bart is now doing when he initiate a conflict right before his war? Most people would finding razes into wars more of a reason to get back at you than someone robbing gold.
I really doubth the U will want to wait 2-3 weeks while Bart raze this kingdom to the ground, and other robbers will know he can most likely not raze several kingdoms at the same time, this is why razing into wars is something you do when all other options has been exhausted and not as a form of greeting.
