In fact, for Mexico, it is not important whether the immigration wall can be repaired. After all, it was fixed. If China people can't get out, they can develop at home with peace of mind. If it can't be repaired, it is right for China people to continue to flee to the United States to seek a life. Mexico knows it is indefensible and its public security management ability is poor, which leads to a large number of drug trafficking and drug abuse, and there are too many criminal gangs. So Mexicans rack their brains to make a living in the United States, and Mexico doesn't care about these very immigrants and stowaways.
For the United States, these immigrants bring drugs, crime and rape! It can be seen that Mexico knows how much harm these illegal Mexican immigrants have brought to the United States. If Mexico stands up and speaks, it is completely self-defeating! Even Trump will let them pay for this wall.
In the international community, the United States has not given Mexico any face. After all, this thing is really too much. Trump's move is to simply and rudely tear off the fig leaf of Mexico. The more Mexico opposes it, the more it proves its guilty conscience and the more it admits its domestic problems. The construction of the border wall by the United States actually helped Mexico to some extent.
