Mods, I think there is a factual answer regarding what the UN will and will not do.
I was in San Jose (Costa Rica) last week on business, and I remembered that they have no standing army. When I asked a local businessman how secure he felt having no military he said that they are friends with their immediate neighbors, Nicaragua and Panama, and that if they were ever threatened that the UN would step in to protect them.
I was stunned by his answer since I don’t think the UN would be willing, or able, to stop another country from invading. Am I off base, or is the UN somehow chartered to protect a member nation that is attacked?
I realize that Costa Rica is considered a neutral country, but a belligerent nation could presumably walk in and take over with little resistance. That wouldn’t make me very comfortable.
