Right. Given the infiltration of Hamas/Jihadis, Chinese, and the cartels, Russian Weapons and planes in S. America, it is very possible that caravans and coyotes are not the only purpose of the troops at the border.
Terrorists and Cartel had plans to cross the border and start attacks around the time of the inauguration. Fortunately, those plans were discovered and stopped.
When Trump was elected, I pointed out that America was weaker than ever before. So I fully expected, if they were going to attack it would be then.
Antifa was also an attempt to get civil conflict going - if they are ever successful, that would be another time of danger for invasion/attack.
If DEMS don’t win, I expect more bad behavior from Antifa. If it gets out of hand, there could be Martial Law in some of those blue cities.
With the g/20 summit coming up, and the Fed trying to start a recession, I expect the Globalists are going to try additional economic warfare, so everyone should just make sure to have some extra cash, food, water etc. in case of disaster - natural and unnatural.
RE the purpose of the military at the border:
THANKS FOR FILLING IN THE DETAILS! :-D
