David P. Goldman (pretends to) channel Oswald Spengler. He often writes interesting columns, in this case for PJ Media. And yes, his work is often pessimistic.
Here his topic is the lack of trustworthy Arabic speakers in the U.S. By "trustworthy" he means other than first or second generation Arab immigrants. Such individuals are often suspected of being al Qaeda moles.
Interestingly, Israel has a surfeit of non-Arab speakers of Arabic. The U.S. could hire these if it weren't that they are also viewed as untrustworthy - remember the Jonathan Pollard case. Spengler likens this situation to Gulliver tied down by Lilliputians.
If the U.S. government needs Anglos to learn Arabic, why doesn't it train them or subsidize the learning thereof? We know from economics if you subsidize something you will get more of it.
