Back in the 90s, an American socialist tried to tell me that the Berlin Wall was constructed to keep the westerners out. I told him is BS wouldn't work on me because I've seen the Wall myself in 1969, went through it, and toured East Berlin.

It's a shame the Berliners tore down the Wall so fast, though I totally understand why. I would have kept the section on Bernauerstrasse as a reminder for the revisionists.

Setting all bloviation aside, you can judge a country simply by does it have walls to keep people in, or walls to keep people out.
