The irony is that there is absolutely no such thing as a Sunni Islamic system waiting to be implemented. "Islam" is a useful slogan (once very fondly embraced by the CIA for its own purposes) and will no doubt continue to be used as a recruiting and motivational tool by many organizations and individuals, but contrary to popular belief, there IS no such things as an "Islamic system". The existing works of orthodox Sunni political and legal thought were composed in medieval times and assume the existence of some absolutist ruler (usually monarchical, some are anti-monarchical) and social and economic circumstances that approximate the 12th century CE. NOTHING exists beyond that.
There is no there there.
