The US-Mexico War caused Mexico to lose half of its territory. What was Mexico's attitude towards the United States at that time? Pro-American or anti-American?

The mentality is complicated, Mexicans are lazy, and those places are second-rate countries. Backed by such a world superpower, the mentality is nothing more than flattery and inner jealousy. People sneak into the United States every day on the US-Mexico border, and the conditions for being arrested and imprisoned are better than those in Mexico. California even set aside a pedestrian zone in the middle of the highway to prevent these stowaways from being killed. If the United States calls Mexico again, it is estimated that it will be very happy to work directly in the United States. After all, the price level in the same country will not be very different, but I will definitely think about what I was rich in the past.
