Things That Make You Go "Wow!"
The Nation printed an insightful essay on the changing face of war by Barbara Ehrenreich. I urge you to read what Professor Ehrenreich has to say. It's lengthy, and it's not beach reading, so be prepared to spend some time reading and digesting her analysis.
What I found fascinating was the last section of the essay, the one in which she deals with the latest phase of war-making. With computerization and drones, more and more of the human element is being reduced. Her closing comments (which I will not provide here because it might spoil the fun) contain just the hint of optimism for humanity.
