DoD loyalty test for Jews?

InsightMag.com has a blurb for a subscriber-only article that is troubling, to put it mildly:

Defense Dept. imposes loyalty test on American Jews
The Pentagon has banned security clearance to Americans with relatives in Israel. Government sources and attorneys said the Pentagon has sought and succeeded in removing security clearance from dozens of Americans, mostly Jews, who either lived, worked or have relatives in Israel. Official documents report that American Jews were asked by Pentagon examiners whether they would join a U.S. attack on Israel if the Jewish state was threatened.

Over at Free Republic there is some skepticism about this, both about whether it is true and whether it is standard operating procedure for all employees with relatives in other countries.

I would love to know whether Americans with Canadian or British or Australian relatives have to answer the same question. The question isn't dual loyalty - it is whether Jews are being discriminated against by our own government.
