Mexico is conducting a "war by other means" against the United States. Ask any Border Patrolman. If you don't buy it, tell me.....how many Mexican cities are now "ethnically American", and have American politicians ruling over them?
War can be conducted in many ways. The Mexican Caudillo's are using their strength - millions of people - and exploiting our weaknesses: U.S. civil rights laws and political correctness that stops us from retaliating against them.
And that is the real reason that "violence on the border is increasing". The thugs smell weakness....so they go for the throat. They aren't afraid of U.S. law enforcement anymore. And included in the ranks of the thugs is the entirety of the Mexican "government".
They might also be smelling resolve for the first time. It's about time we stood up to them and protected our borders...
No doubt that these thugs will be picking up some NWO financing soon. So when America falls into Soviet style disorder they can swoop in again and pick up some real steals.
