Sounds good, but we need to see real results within a month or two, otherwise it won’t be unreasonable to suspect Mexico of trying to run out the clock if they don’t really crack down immediately. And at some point they will have to use some unpleasant level of force because they tried to close a part of their southern border before and the illegal migrants just pushed down a gate and fencing and walked right in.
This is a move that can be stopped as quick, or quicker than it can be started by Mexico.
Mexico didn’t really try before, that was for show.
Mexico has started cracking down already; it will take a bit for it to make a difference in what we see. The flood will have to recede.
Mexico has made some interesting arrests the last couple of days for human trafficking and relate offenses. https://tucson.com/news/local/migrant-shelter-operator-key-figure-in-border-aid-trial-arrested/article_0157c1d4-8807-11e9-8bb2-e339c7e447b9.html
I do not trust Mexico but we shall see.
