It's really long for a wall, isn't it?
Still, the sides always seem to end up blending together and eventually both sets of folks settle reasonably in accord.
After that happens, the wall simply moves to a new venue: Jericho, Troy, Berlin, and why not one for Mexico?
I guess who and what rests behind the wall is ultimately no different or more important than who and what is in front. It just takes time to process and believe it, that's all.
And that concludes my in-depth political analysis of this breaking situation. :)
