Well W.W. II was a different thing, but to the point of this, these are not by definition Internment Camps.
But there is an idea, I proposed this over the weekend as one of the options. If they want all these families housed together then, yes, you have to build and maintain large Internment Camps for all of these people.
Otherwise you send them back across the border, or just have open borders and give up.
None of the people. Laura Bush included, have not offered any idea to deal with this that they will accept.
And build them south of the border.
Yes, a lot of carping, but no solution.
