Politicians can only react
The President of Mexico now has grounds to react strongly. His citizens are now being harmed
Yes I think this may lead to them securing their Southern border again. They can secure it, have in the past for many years. When illegals were allowed to pour in they didn’t care if they crossed Mexico and didn’t see it as their problem. Now they have to deal with them for who knows how long so it is their problem. Not to mention this group has caused problems all the way for Mexico.
It would sure be great for us if Mexico would secure their border to Central America. Would not solve all the problems of the border of course but would better allow us to deal with that if we don’t have large groups of other people trying to get in.
