Secure Borders

In RFE-RL's latest Afghanistan report, they have a short article on the state of the country's drug trade. I don't really have much analysis of it, and my own opinion that we should consider making Afghanistan a treaty supplier of opium has been states elsewhere. However, take note how it's smuggled through neighboring nations, especially Iran. Iran definitely does not want all that opium and heroin in their country, and yet the percentage that does pass their borders has increased. Where I'm going, of course, is that borders are not airtight, and the fact terrorists or other kinds of militants may slip across a country's frontiers does not mean that country is aiding terrorism.
