If the United States of America wanted to secure it's borders you would not need a fence, or wall, or anything else.
It's a simple as that. We all know it, if you don't know it, think about it for a minute, you will realize it.
There are reasons the borders are open, and it has nothing to do with not having the "power" to keep people out.
Until such time as our government decides to secure the borders, anything we do is a waste of money and just for show.
We have lost our sovereignty, and that is a direct violation of all of our rights, and is an embarrassment to any clear thinking American.
