I suggest we try not to do anything prohibited by the United States Constitution, which that is.
Our elected officials take an oath to protect the sovereignty of this nation. So far, I don't see very many of them even coming close to doing so.
And having the military defend our borders during a war would be unconstitutional how?
I really don't understand what you are getting at with your comment. After all the illegals scream for civil rights which are not the same as constitutional rights.
Since they are alien nationals, I'm not sure that Constitutional would apply. Maybe International or humanitarian laws, which would be that they should immediately be humanely deported? Either way, they've gotta go.
