what do you not understand about MAYBE? It's a non-commitment.
What I don't understand is how "maybe a fence" adds up to his campaign promise. Trump promised a tall, impenetrable wall, complete with under ground sensors and all kinds of fancy technology.
What you refuse to accept is Trump, even though he's a builder, doesn't understand some of the natural barriers that exist on the border. The whole border isn't flat desert land where a wall makes sense. There are very rugged mountainous areas where you can't move easily or quickly across it, drones would be more effective in those areas.
A barrier can be built anywhere..Drones will be used as well
Sure but why waste the money if a barrier already exist? Do you put burglar alarms in your attic or on your walls?
