It's not as simple as the US covering for the Mexican Army. Mexico as a country is broken and is the new Columbia. So far our government is not willing to admit that to the American people.
There is still this pretense that Mexican officials are in charge and we can negotiate with them and support them to make things better in Mexico, which would in turn solve most of the border issues. It is time our government admit the fact that Mexicans officials have lost all control of the country to drug lords and mafia types, and tell the American people the truth. We have to deal with Mexico as it is today, and not how we wish it could be.
What you are seeing in D.C. is an effort to support the figurehead Mexican government, but the truth is, it is too late for that. We the people need to let our politicians know that we know the truth about Mexico, and we need to close the border to keep their violence from spilling over as it is now. Whatever can be done to help Mexico with their problems will be an issue we will eventually have to deal with, since they are next door. For right now, the most important thing is to get the border closed and then see what else needs to be done to protect this country.
...What you are seeing in D.C. is an effort to support the figurehead Mexican government,...
What you are seeing is bi-partisan treason.
The plan is to eliminate the borders and create a continental Socialist hell of a Community.
Sidestep the Constitution, eliminate the need for re-election, and the American taxpayer will be bled to death paying for it all.

Add "Phyllis Schlafly" and you'll be directed to an excellent summary of the whole disgust thing.
