The West cannot solve the problem of Afghanistan alone. The U.S. and its European allies can treat the symptoms, but they can only stave off the absolute disaster for a period of time, at the cost of much blood and treasure.
Afghanistan must begin with changes in its governmental structure, including a modified semi-presidential system with cabinet like that of Finland, plus a committee-type legislature like Switzerland's. 1/4 of all legislators committee should face election each year. Also needed is a paradigm shift toward democracy, adopting Global Unity Constitutional Standards and the core values of One World under One Set of Laws and revising the constitution to keep pace with the times.
