Democrats in US Congress wrote to President George W Bush, expressing concern about spiralling violence and drug-trafficking in Afghanistan, which they said is quickly becoming a "narco-state."
"The huge profits from the opium trade are funding the implements of terror for the Taliban, Al-Qaeda, and criminal gangs that are preying on the innocent and killing our people, coalition allies, and Afghan soldiers, officials and civilians," the lawmakers wrote on Tuesday.
"They are well on their way to creating the world's first true 'narco-state', whose economy and politics are almost completely dominated by the drug trade," read the letter signed by Tom Lantos, top Democrat on the House International Relations Committee, and other Democratic committee members.
"The dreams of the Afghan people for peace, security and a better life are drowning in a sea of violence, corruption and opium poppy," the lawmakers wrote, blaming a weak and corrupt central government, and a resurgent Taliban Islamist group, among other factors.
"It is clear that the United States and its coalition partners are simply not doing all that is necessary to prevent Afghanistan from lapsing back into lawlessness and a sanctuary for terrorists," they wrote.
The Democrats called for a "bottom-up review" of US Afghanistan policies and programmes and an increase in funding to fight narco-traffickers and narco-warlords.
