I do not believe that alien is synonomous with ILLEGAL IMMIGRANTs on American soil.
I think alien just means foreigner.
Regarding the illegals here, we should feed them, clothe them, give them medical and financial help and send them home unless they are political refugees or truly coming for their lives.
No one has a right to take from others to the point they are becoming impoverished, which is what is happening to the lower and middle class in America. Every year a million more people go on the poverty rolls, as a million illegals come in.
Isn't a foreigner an alien?
