Well for one thing, this is an example of Jones talking up his mormonism. My guess is that this was originally presented to a majority mormon audience.
The "secret combination" stuff is a very real part of mormon doctrine. Like most of christianity we believe that the world is going to go down the crapper just before Jesus arrives to clean the mess up. This includes global takeover attempts by one or more factions that are up to no good. Generally, mormons don't dwell on this aspect of our faith with the intensity that the protestants do with things like the
"Left Behind" videos and books.
Jones's take on the "secret combinations" seems unusual for members of our faith.
Ezra Taft Benson (Secretary of Agriculture under Eisenhower before becoming president of the church) stated that this secret combination prophesied in the scriptures was international communism. He was joined in this assesment and in condemnation of the United Nations by fellow high-ranking mormon, J. Rueben Clark (who also served as Undersecretary of State and US Ambassador to Mexico). Mormon endtime prophecies also speak of a final war against Isreal in wich she will have few if any friends or allies much like the rest of christianity. These days, the leaders of the church are reluctant to identify who and what this secret combination.
Whacky conspiracy theories in the US (and to a lesser extent, Canada) have traditionally come from the right. 9-11 conspiracism is different in that it's probably the first equal opportunity looney bin. The actual card carrying communists, few of them there may be, are in full support of the 9-11 theories. Furthermore the 9-11 "truth" movement is the most anti-isreal of the conspiracy nuts and probably would have been without the involvement of the stormfront.org pinheads. According to
http://www.geocities.com/debunking911/ the only people who have reviewed and passed Jones's original paper is a
marxist website.
This is mostly circumstantial and I can't really know what's going on inside Jones's head. But turning against the most anti-UN administration in recent memory, joining up with the commies and the anti-semites just goes totally against the grain for someone who claims to be a conservative mormon.
I have no evidence, just my gut instinct and personal knowledge of mormon culture. So take it all with a grain of salt.
