The United States-Mexico War partially abides by this principle. Although the United States and Mexico wished to resolve the territorial dispute peacefully, the two nations resorted to the use of force. The United States sent an envoy, John Slidell, to Mexico in order to annex Texas, New Mexico, and California diplomatically. However, the Mexican government refused to accept the envoy since the public was against Texas annexation to the United States. Although Mexico warned the United States that Texas annexation would be a "declaration of war," the American government signed an annexation treaty with Texas in 1846, which caused the Mexicans to use military force to protect its territorial integrity. Therefore, the Mexican-American war could have been prevented had the United States regarded the Mexican admonitions seriously.
