Take out the supply line. They aren’t carrying food/water and the places they pass don’t have that much extra.
If we can’t take out the staging areas and/or vehicles without being detected we have much bigger problems in our military than 7000-14000 future Democrats marching through Mexico. And if we can take it out they stop in 1-2 days
Another Freeper had posted some of the logistics required to move 5000 people from Honduras to the US.
Simply put, 5000 people on foot cannot make it that far without help.
It's 2,558 miles from the US to Honduras.
In WW2 the Germans would march up to 25-30 miles per day in their invasion of the USSR and they had a logistics train to support them.
If the average walking speed of a person is around 3 mph and they walked for 10 hours a day it would take 85 days to cover the distance....and this is a healthy person.
Simply put, the "caravan" has to be financed, feed and transported.
How I wish we had aerial coverage of this invasion.
