An Iron Curtain.

       President Trump is now asking for a steel barrier instead of a concrete wall. Steel or Concrete, what's the difference? The former Soviet Union, Russia, built one, it was called the Iron Curtain. It failed. The question is this; do we want all the world leaders standing on the Mexican side hollering "Mr. Trump, Tear Down this Wall!"
       And all the worlds leaders will do it because we will have no friends left to stand by our side. We won't have friends because Mr. Trump will have alienated them all. Just think back to when President Reagan uttered those words to President Gorbachev. Tear Down This Wall. And the Soviet Union, in shame, tore down the wall, or rather, allowed it to be torn down.
       "Mr. Trump, Tear Down This Wall!" A better way would be to say, Don't build it in the first place. We need border security, that's for sure. We need it along the Mexican border, we need it at all our seaports and we even need it along our Canadian border. Not all to the same degree, but we need it. We can't build walls at New York City, or Boston, and we certainly can't afford a wall all along our Canadian border, but we need security. So lets stop acting silly about a silly wall and start considering smart technology. Build walls in places where they make sense and more 21st century security elsewhere.
       What we don't ever want to see is the whole world standing on the Mexican side yelling "Mr. Trump, Tear Down This Wall." It would be embarrassing. We don't need an Iron Curtain along any of our borders. We're not isolationists and never will be. So Mr. Trump, Stop Asking For an Iron Curtain Wall.
