We know that the border is a mess, but Fox is reporting that the Biden team is considering sending up to 1500 US active-duty troops to the border to help with administrative and transportation issues.
They report that most of these migrant critters are Venezuelan, but we know that the border is controlled by the cartels, and at some point we are going to have to deal with that fact. The Mexican government is either unwilling or unable to deal with a large criminal enterprise on their northern (our southern) border.
There is historical precedent for dealing with problems like this. In 1916, there was a cartel in Mexico that was causing havoc along the border and the US Army sent a punitive expedition to take care of the problem.
That expedition didn't go exactly as planned, but it did do some good. I'm just saying.
