this and this.
Note the self-comparison of their mission to the Legion of Super-Heroes. They were also teen-agers out to save the world (but really, they just enforced the status quo). An unfortunate comparison. Is that real irony or Alanis Morrisette irony? I can never tell.
Given the seriousness of the soldiers' location the comic book referenced response from Editor Mort Weisinger to the 'unsolicited' missive seems a little inappropriate but was likely sincere. It also seems carefully neutral since you couldn't expect too much overt in-depth political & social commentary either pro or con in a comic book of the era...yet. That was still over the horizon a bit.
