It's an excuse to invade Mexico but I think the Mexican government is also not up to fight, they know it will only get worse if they fight the US military. But Gringos are welcome as long as they are also welcome in the country. Fair trade so let's just keep trading the fentanyl both our governments make money! Keeping this up, they will see the conquistadors ruling the entire country.
Why should Mexico stop doing something that is beneficial to them? The corrupt government officials and mafias inside Mexico are benefitting immensely from the migrant inflows. Illegal aliens, especially those who are outside the Americas are paying as much as $20,000 to $25,000 to the cartel members to get them across the border. And anyway, the root cause of this issue is weak law enforcement within the United States. Why should the Mexican administration take the blame for all the incompetence from the other side of the border?
