America refused, reminding the government of Mexico that the terms that had already been agreed to in the Treaty of Guadalupe Hidalgo made America responsible only for protection, not financial compensation for any losses that happened to people or territory belonging to Mexico ("Gadsden purchase, 1853-1854," 2010).
