There can be no more important issue than the issue of war with Mexico, for all other issues are tied up with it. The forces of progress will have to gather swift strength, or they will feel the crunch of the Iron Heel."
-John Kenneth Turner, Hands Off Mexico
In Hands Off Mexico (1918), John Kenneth Turner, who, along with his wife, had long been involved in Mexico's revolutionary movement, sought to plead the Mexican cause during a time when the US government was reevaluating its policies toward Mexico. His pleas for the US to refrain from invading Mexico, played an important role in the drafting of the US Immigration Acts of 1917 and 1924.
