Research in anthrozoology (the study of human-animal relationships) has clearly shown that our relationship with nonhuman animals (animals) is a shambles (see also Animals and Us). Some of the animals we claim we love are brutally abused and killed and the inconsistency between what we say and what we do on their behalf is dishearteningly dissonant.
Let's briefly consider the use of animals as weapons of war. Various animals are used to fight our wars and it's known that dogs, at least, suffer from PTSD when they're done being forced to serve. The popular movie War Horse was instrumental in bringing widespread attention to the use of animals in war and there are many books focusing on war animals. Nonetheless, their use continues.
A recent essay in the New York Times by Philip Hoare titled "Let Slip the Dolphins of War" is a most thoughtful brief piece that raises many of the important questions. It will be read by a wide audience who might otherwise not pay much attention to the use of animals in war, and I was surprised by the wars in which dolphins were used. Much of the use of animals in war is hidden from a largely uninformed public. But, perhaps, no longer will this be the case.
