We are under attack with the massive cross-border invasion and the gargantuan drug flow - a state of war is here and now.
All we have to do is make it clear to the Mexican people that we will welcome them all into the United States and end the rampant governmental bias and corruption while providing them security from the criminals and the Federales, while developing their resources to benefit them all, and the war's over.
Again, it would be stupid and a disaster to invade Mexico.
Best to put our troops on the border and special forces to take out cartel leaders.
Do you know about the Sleeper Cells being set up in the continental US?
