No, saying that fallen military service personnel are “heroes” is not “rhetorically proximate” to justifications for more war. Rather, it is “rhetorically proximate” to saying that whatever one’s feelings about a particular war, the fact that military service personnel gave their lives in the service of their country while being fully and completely aware of the risks entailed in their service of the country makes them brave and heroic since they likely had to face and overcome a great deal of fear in the course of doing their duty. One can hate a particular war, while being entirely in awe of the soldiers courageous enough to fight it.
One is reminded anew of F. Scott Fitzgerald’s famous comment that the sign of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function. But the funny thing is that in this case, saying that (a) certain wars might be objectionable, and (b) the soldiers, sailors, airmen and Marines fighting them are heroic are not even opposed ideas. So it is possible that Hayes has failed to display even a fifth-rate intelligence. Scary stuff.
