Among the options discussed during Arthur Zimmermann's period in office was a German offer to improve communications between the two nations and a suggestion that Mexico purchase German submarines for its navy.
Blandt de muligheder, som blev diskuteret under Arthur Zimmermanns tid som udenrigsminister var et tysk tilbud om at forbedre kommunikationsforbindelserne mellem de to lande, og at Mexico skulle købe tyske ubåde til sin flåde.
