you must not tamper with arrangements
Could translation be off? A word other than fight would seem like a better choice, though maybe the poet trusts that after what's gone before, readers understand it cannot be a violent fight he's referring to, but more one of perseverance?strange ending, no? Seems to be condoning and believing that war is still the way to peace, even though it is war that has killed this child.
