Afghanistan's neighbors are helping destabilize the country as "time is running out" on the U.S. effort here, according to a senior intelligence official with the international military force in Kabul.
The official accused Iran and Pakistan of maintaining links with the Afghan Taliban and singled out Pakistan for providing "insufficient pressure" on Afghan insurgent leaders who enjoy safe havens inside Pakistan -- despite U.S. pressure to expel or fight them.
Iran and Pakistan's relationships with the Afghan Taliban "are destabilizing relationships that are not helpful," the official said, speaking to a small group of journalists on the condition the official's name not be used.
Since President Obama announced early this month he would send an additional 30,000 troops to Afghanistan, senior United States officials have warned that one of the main risks to the Afghan strategy was if Pakistan decided not to crack down on militants who use its soil to attack Western troops in Afghanistan.
But the intelligence official linked Iranian actions with those by Pakistan more directly than most military or civilian officials have done, and did so while painting a dire picture of the state of the insurgency in Afghanistan.
The official described the Taliban an "increasingly confident," "increasingly effective" and "growing more cohesive."
"They've increased their capacity," the official said.
"Kinetic" activity is up 300 percent since 2007, the official said, and up an additional 60 percent since 2008 -- mostly because of a massive increase in the use of roadside bombs.
In 2004, the official said, there were 326 incidents involving roadside bombs, which the military refers to as improvised explosives devices, or IEDs. That number jumped to 1,922 in 2006, 4,169 in 2008 and more than 7,200 in 2009.
And in the same time, the bombs have become more lethal.
From 2003 to 2006, the official said, the majority of IEDs contained 25 or fewer pounds of explosives, usually derived from military munitions left over from decades of war in Afghanistan. But by December 2009, most IEDs contained between 26 and 50 pounds of homemade explosive, and a significant portion of them contained more than 100 pounds.
"We've had 2,000-pound bombs take out one of our MRAPs," the official said, referring to the military's safest vehicle, designed to withstand the destructive power of a roadside bomb.
"Whoever is [the insurgents'] logistics chief, we ought to take lessons from them," the official joked.
The military has come to terms only recently with how effective the Taliban has become in targeting Western troops and in exploiting vacuums created by a weak and inefficient Afghan government.
That effectiveness has contributed to a doubling of U.S. fatalities this year over last year. It also has allowed the Taliban huge influence across southern and eastern Afghanistan, where there are pockets of space entirely controlled by the Taliban -- though some of those pockets are beginning to decrease as more United States troops arrive in Afghanistan.
The increased Taliban effectiveness has allowed the Taliban to expand its influence to western and northern Afghanistan, where it has historically been the weakest.
