What is the central message of 'No Men are Foreign?"

The central message of
the poem is that war is a mistaken notion because all people on earth are connected through
their common humanity. The poet describes a number of similarities that we share with our
supposed enemies. The poet notes that underneath every soldier's uniform, the soldier breathes
as we do. The soldiers who oppose us all walk on the earth, as we do, and they also share the
sun, drink water, and enjoy the harvests of the earth. In addition, we share similar body parts,
such as hands that labor and eyes that wake from sleep.

After drawing all
these similarities, the poet asks the reader to recall that when we are asked to hate others, it
is really ourselves that we hate. If we fight each other, we destroy the earth that we share and
destroy innocence everywhere. When we fight others, we forget that our enemies are not foreign
but are like ourselves.
