A Christmas Hymn

I was on Christmas Island during the American Nuclear Test series (Operation Dominic) in 1962. The poem is actually attributable to an unknown Yank. My rank was SAC and resided at the RAF lines at Port. I was on the Island between March 1962 and March 1963. It will only be fully understood by someone there at the time, and if I can help to explain any of the content please shout. An enjoyable website by the way, which brings back memories of my year on the rock.
