This article by Betty Reardon is the second in a series exploring Betty’s 6 decades of peacelearning. In this post, Betty comments on “Peacekeeping,” a curricular unit in the secondary school series on “Perspectives in World Order” published in 1973. Betty’s commentary here focuses on two excerpts examining approaches to peacekeeping and alternative security. We post this article on the cusp of the 100th anniversary of “Armistice Day,” which marked the end of fighting in WWI (Nov. 11, 1918). The “War to End all Wars” turned out to be a false promise as evidenced by the persistence of major wars throughout the 20th and into the 21st century. We have much still to learn from this tragedy, and it is our hope that Betty’s inspiring and practical vision for “Teaching about Peacekeeping and Alternative Security Systems” might help us in that journey.
