With the US military's recent emphasis on counterinsurgency and policing actions, scores of books have examined "small wars" in Malaysia, Vietnam, Algeria, and the Hejaz War of 1916. Still, there are far more conflicts worth studying, with the actions in Northern Ireland being among the most valuable, and the narco-insurgency in Colombia being a close second. My regular readers also know that I also draw a lot of parallels between modern counterinsurgency and the American Revolution.
(As an aside, I'd argue foremost among the lessons worth drawing from Northern Ireland is that the tensions between Protestants and Catholics have little to do with religion, per se, but with deeper-rooted, more practical motivations, such as economic factors and political power-sharing. For example, unemployment among Catholic youths in Northern Ireland has skyrocketed in recent years, according to the New York Times. I've long believed a similar situation exists in the Muslim world, with religion used largely as an excuse, not a motivator, for violence)
What other "minor" conflicts are often overlooked in contemporary military studies?
