@GlassAxe- You make a couple of interesting points, particularly pertaining to the reasons people in other countries get into the drug trade. If you look at any of the major drug exporting countries, they are often underdeveloped and blocked from future development because of hefty debt from lopsided development loans.
The quickest way to win the war on drugs, and extremism, is to create trade agreements that actually allow other countries to participate in fair and free trade. In some nations, illegal drugs are their only marketable good because wealthy nations are able to subsidize many of the goods that enter the world market. In these cases, highly addictive drugs that are illegal in developed nations demand a high premium. In a way, drug trafficking in the U.S. is the result of us dominating international development.
