I don't typically agree with Kraut on much but on this one I do.  Trump wants to build physical and metaphorical walls and seal us all inside with him.  What a frightening thought!  We are an exceptional country because we reach out and help others, a not entirely altruistic effort as Kraut claims - we do indeed benefit from that.  America will never become great "again" by sealing ourselves in a box and hiding from the rest of the world.
