-mark twain, \the war prayer\

Explanation:

Sarcasm is saying the opposite of what is meant. In the text, asking God “in the spirit of love” to bring destruction is sarcastic. Love is typically associated with positive, non - harmful actions. Here, using “love” to ask for destruction (tearing soldiers to shreds, laying waste to homes etc.) is a contradiction. Praying for victory instead of peace is a more straightforward request (not sarcastic in the same sense as the “love - destruction” link). Asking for protection of soldiers is a normal prayer (not sarcastic).

Answer:

asking God, "in the spirit of love," to bring destruction
