Reddit frequently solicits from its subscribers amusing captions for unusual photos. On January 24, it offered a picture of what appears to be two armies of penguins charging into battle with one another, or perhaps charging into a group-hug contest.
This candidate inspired some speculation about obscure wars that led readers to my old blog post on the war between Liechtenstein and Italy, in which Liechtenstein suffered negative casualties because its army made a friend on the way.
This was apparently intriguing enough to garner 600 hits in the last three days, making it one of my most popular blog posts to date. (Though it still has a ways to go before it can compete with my post on the Imperial Russian Navy and its pet python.)
All of this suggests that:
