I am not a Bircher, but I have read the New American for the past 25 years. It is one of the most informative magazines, well written, well researched, and pro American magazines that is out there. I have never noted evenf a hint of anti-Semitism or racism. And their articles on History are second to none.
True, it isn't openly anti-Semitic, but it peddles a "conspiracy theory" that often turns people anti-Semitic. And it is certainly not friendly to Israel. It represents a continuation of the pre-WWII right and leans heavily to chr*stian reconstructionism rather than conventional Fundamentalism.
I continue to maintain that the JBS and its organs are very inconsistent in their position on "American interference" abroad. The JBS had an organization in the Eighties called the Western Goals Foundation which was all for American aid to anti-Communists in Central America. But when it comes to Israel and the Middle East, they are strangely isolationistic.
