Our government does not want the borders secure.
There’s lots of conjecture as to why, I will leave that for you to decide.
Democrats nor Republicans have done squat.
State Dept says, “Oh, they just wandered into the US, didn't know they crossed the border. . it's just a big mistake.”
This enrages me to no end that our own State Dept, our LEFTY State Dept, makes excuses for the Mexican Army as they escort drug smugglers into the US.
The border is well marked, every inch is marked by a well-defined and wide road along with, at the very least, barb-wire fencing. Oh, and the Mexican Army is driving Hummers we gave them, and they all came with GPS (most likely sold to the cartels, just like their weapons, also US supplied).
