Obama's speech yesterday in Berlin, hailed as a "major" address, has at least one major, glaring error that shows that nether Obama nor his handlers and speech writers were thoroughly familiar with the facts. Obama's main theme was about the "walls" that separate all of us one from another. He claims that many of these "walls" have been taken down and hails that as progress. But in at least one instance he is wrong. In fact more walls have been built where Obama claimed they were taken down.
