Answer:
War is tragic, tribulatious, and cataclysmic; it should not be glorified; however, we should not forget the various and steep sacrifices that have been made for war. Memorials are there to honor the fallen and all those who have given a part of themselves to the occasion. Thus, no, these monuments and memorials that were enacted to honor those in war, do not contradict the message of "Grass," for it is there to bring light on the fact of how catastrophic war is.
