What literary device is a parent in the title of the poem in the war is kind and what effect does it have on readers interpretation

The literary device that is present on the title of the poem "War is Kind" is irony.

Irony is the expression of one's meaning by using language that normally signifies the opposite, typically for humorous or emphatic effect. This idea of expressing the opposite of what is actually being said/wrote is present on the title: in this case, by the use of the word "Kind".

The ironic title then conducts the reader's interpretation; it signals the ironic intent and makes the reader more aware of the ironic elements on the poem.
