The World War I song above tried to glorify war in order to get Americans to join the military and fight. To glorify war means to A. make it sound exciting and thrilling. B. tell the truth about the horrors of war. C. make people stop fighting each other. D. tell only the bad things about war.
Glorify means to only tell the good things and "make it sound exciting and thrilling" is telling good things about war when in fact war is destructive and brutal.
