Never short of guns and guerrillas, Afghanistan has proven fertile ground for a host of insurgent groups in addition to the Taliban.
After the Soviet withdrawal, many Afghan Communists had rebranded themselves as Islamists and joined the mujahedeen.
Some people will talk about how Afghanistan has improved, but they're really just talking about the cities. In the countryside where the war has been fought, it's really not that much better than it was in 2001.
The existence of the Taliban, in my view, is a tragedy for Afghanistan. We as Americans need to understand our role in helping bring that tragedy about. So I think it's important to look at the stories about why these people are fighting.
A military base in a country like Afghanistan is also a web of relationships, a hub for the local economy, and a key player in the political ecosystem.
In 2012, I received a phone call from the family of Arsala Rahmani, the Afghan senator with whom I'd become friendly. That morning, a gunman had pulled up alongside Rahmani's vehicle, idling in a crowded intersection, and shot him point blank.
Afghan human rights campaigners worry that U.S. forces may be using secret detention sites like the one allegedly at Rish-Khor to carry out interrogations away from prying eyes. The U.S. military, however, denies even having knowledge of the facility.

It is the responsibility of Afghanistan's new government to gain better control over the country's administration and to resolutely fight the drug trade and corruption.
