I understand your point, but still.. It kinda had to be said out loud, otherwise many people will consider it. Atleast I can never let a good idea go unevaluated.
Conquering Andorra is a bad idea. Andorra has no military, so, through diplomatic arrangements, France and Spain are responsible for the defense of the country. Dogbert's mercenaries may be able to take Andorra, but they would have a hard time defending it.
