Trump is waffling on the wall.

[abaris]

Yes, those areas did exist, where it was built.  I;m not trying to tell you that the wall was n your head, abaris...only pointing out that it was as porous as any wall is, and that it's value was not in being a wall, but in the psychological effect cuch a wall had on people.  Look, for example...at how large you imagined it to be.  Well, it wasn't...but if you grow up around a portion that gets some love it;s easy to think that it is....that it;s such a complete and utter divide that there is no point to go where it doesn't..somehow, exist as you perceive it.

I more or less travelled the length of it and beyond to the other side. Layered defenses, mine fields, guard turrets, searchlights and heavy patrols were more or less state of the art everywhere.

Of course there were instances when someone made it over. But these were a few hundred in a period of over 40 years. And they learned from their mistake. If one attempt was successful, they made sure that a similar attempt would fail.

I'm not debating the value of the Iron Curtain here, I'm mainly debating that it isn't feasible if you put your mind and funds to it.
