In 2007 an dire article from Seymour Hersh:http://www.newyorker.com/magazine/2007/03/05/the-redirection
" To undermine Iran, which is predominantly Shiite, the Bush
Administration has decided, in effect, to reconfigure its priorities in
the Middle East. In Lebanon, the
Administration has coöperated with Saudi Arabia’s government, which is
Sunni, in clandestine operations that are intended to weaken Hezbollah,
the Shiite organization that is backed by Iran. The U.S. has also taken
part in clandestine operations aimed at Iran and its ally Syria. A
by-product of these activities has been the bolstering of Sunni
extremist groups that espouse a militant vision of Islam and are hostile
to America and sympathetic to Al Qaeda."
