Thomas Merton was very vocal, in print, in his opposition to the Viet Nam War in the years before his death. As vocal as a monk under a vow of silence could be, anyway. He believed that ending the draft would reduce the temptation to get involved in more Viet Nams.
I wonder what he'd make of our all "volunteer" military. If we don't have enough personnel in uniform to do the job; we outsource it. Usually at a much higher cost than we'd pay if we had military personnel to do the jobs.
Reminds me of the paintings of the flagellants who crisscrossed Europe after the plague years in the fourteenth century. Back and forth, back and forth led by skeletal figures offering some sort of redemption.
What redemption will we find as our voluntary wars wind down? We can be free or we can be safe. Sometimes both, but never for very long.
