So where do we stand on the group of people traveling north to America ?

A country has the right to close its own boarders .
And if you have thousands that claim to be getting away from bad governments / etc ......fix it.
Are we required to let them in ?
The wall ...... for everyone that is up in arms about this , remember their was a HUGE divider for a thousand years - The Rio Grande.

But that has all but dried up , so what if it is replaced now ?
