The symbolism of a wall is important. Barbed wire, like the wall itself, sends the message

What i take away from this: The symbolism of a wall is important. Barbed wire, like the wall itself, sends the message "there is a border here which we intend to enforce." That's another reason to build Trump's wall: the symbolism. It's not a bug (undiplomatic!). it's a feature. https://t.co/90sFboqhTL
