I'm in favor of legalizing/decriminalizing drugs (and heading down to the reform conference in a few hours, in LA --
http://www.reformconference.org/ )
It's crazy that we fight a war in Afghanistan where the enemy is largely financed by two of our addictions (oil via Saudi contributions to AQ, and opiates via the Taliban), and our own logistical footprint (10% of the logistics budget of the US presence goes indirectly to the Taliban!).
The war on drugs, in addition to being ineffective, is racist and immoral.
However, even though drugs is how they started, there are criminal/terrorist organizations, like MS13 and Los Zetas, which are a threat to the stability of some fairly weak states, a source of violence in US and foreign communities, etc., which need to be destroyed even after drug funding is cut off.
The relevancy of all of this to Hacker News is becoming really strained, though.
