Imagine that you are a journalist reporting on the Thornton Affair the week after it happened. Create a newspaper headline from each of these perspectives:
Pro American:
Pro Mexican:

American Newspaper-American troops were viscously attacked and killed on American soil. The Mexican army ambushed our men with a larger force, and now we have to respond. General Taylor and President Polk must take strong actions to prevent such a crime from happening again. War may be inevitable.

Mexican Newspaper-The Mexican army successfully defended itself from an invasion. American soldiers were on Mexican soil without permission and deserved to be attacked. Our nation must defend itself and has a right to do so when invaded. We regret the loss of life, but America seems committed to aggressive acts. We will defend our land!
