Yes. We not only need to seal the border, right now we need to actively protect it.
If we made this a true military mission, we could do it. We’d need to develop speccialized training, plans and maybe even equipment, then rotate units in there for a couple months at a time.
There is a WAR going on in Mexico and it is about to spill over into our countries. And our government does nothing?
We need to look at this as a civil war for control of Mexico. There may be a central government in Mexico, but its control is becoming little more than it was in the early part of the 20th century. Large scale gun battles, political assassinations and frequent killing of law enforcement sure sounds like a civil war.
The worrisome thing is, if we accept that this is a civil war, then the illegals would be considered refugees fleeing from violence, rather than people coming here for economic reasons.
