Yes, it does.
After a brief period of friendliness to Israel during the Begin years (and a brief period of flirtation with respectability during the Reagan years) the JBS has morphed back into the pre-WWII right wing, opposing everything they supported during the Cold War.
The Birchers have always insisted that all our conflicts were phony with the same "Insiders" controlling both sides, but they treated the conflict with Communism differently. Despite both sides being run by the Rockefellers, they supported the draft and US aid to anti-Communist insurgents. With the Nazis and moslems, however, they simply refuse to take part in any conflict since it's allegedly phony and controlled by the same people. So why did they treat the conflict with Communism so differently?
I think that what it comes down to is that despite its alleged non-anti-Semitism, they're opposed to any conflict in which Jews might benefit. Did they then support the "phony" war on Communism because they thought Communism was Jewish?
I used to be a Bircher, and my coordinator told me that there were high Birchers who did indeed believe that "the conspiracy" was Jewish. If you go to their web site you'll find that these people have taken the Society over. It's no different than the Liberty Lobby now.
