New Mexico is west of Texas, but, Mexico is south of Texas.
It didn't work that way: Mexico and the United States started as independent countries; when Mexico got its independence from Spain in 1821, most Southwestern US was part of Mexico. In 1853 Texas split to become the "Republic of Texas"; later, the US annexed Texas and a war broke between the United States and Mexico between 1846 and 1848 (the Mexican-American War). Mexico lost such war and the territories of California, Arizona, New Mexico, Utah, Texas as well as parts of Kansas, Oklahoma, Wyoming and Colorado then became part of the US.
