U.S.-Pakistan ties are virtually frozen. And now, relations between Afghan President Hamid Karzai and Washington are once again getting frosty.

Over the weekend Karzai surprised the Americans with the demand that the largest U.S.-run prison be turned over to Afghan control much sooner that planned.

It's the latest in a series of announcements by the Afghan government that sometimes appear designed to embarrass and annoy U.S. officials, as well as complicate American plans to withdraw troops from Afghanistan.

The heavy, mine-resistant vehicles that almost all U.S. military personnel use to move about Afghanistan are gas guzzlers. And even though the U.S. military buys that fuel at a reasonable price, the energy it takes to fly it and truck it to remote parts of Afghanistan drives the price into the stratosphere.

There's also a much greater cost, says Ray Mabus, secretary of the U.S. Navy.

The mountains along the border between Afghanistan and Pakistan would be cruel enough without the war raging on below — cliffs drop from 8,000-foot peaks that are spotted with only a few trees among the rocks.

But Afghanistan's eastern border has become the focus of the conflict as militants plot their attacks inside Pakistan, then slip across the rugged frontier to carry them out.

In Afghanistan's southeast Paktika province, Forward Operating Base Tillman looks across toward Pakistan over craggy peaks that American troops have nicknamed "big ugly" and "big nasty."

This week, Afghan President Hamid Karzai announced the pardon of a 19-year-old Afghan woman who was imprisoned for adultery after being raped by a relative, in a case that has attracted international media coverage.

But what happened to the woman, Gulnaz, who has been in prison for two years, is not an isolated episode.

Many other women have suffered similar fates. A recent U.N. report suggests that laws to protect women in Afghanistan from rape and forced marriage are still not being enforced — with devastating results.

This past summer, two assassinations paralyzed the southern Afghan city of Kandahar with fears of a power vacuum.

In the first incident, President Hamid Karzai's half-brother, Ahmed Wali Karzai, considered the unofficial kingpin of the south, was gunned down in July by a close associate. Two weeks later, a Taliban assassin killed the city's mayor, Ghulam Hamidi, with a bomb concealed in his turban.

Villagers from a violent part of southern Afghanistan say that Afghan troops, along with several American mentors, forced civilians to march ahead of soldiers on roads where the Taliban were believed to have planted bombs and landmines.

No one was hurt. But if the allegations are true, the act would appear to violate the Geneva Conventions governing the treatment of civilians. The episode also raises questions about how civilians are caught between the two sides in the war.

Performance artist Aman Mojedidi moved from the U.S. to Afghanistan in 2003, as one of what he says were many Afghan-Americans and Afghan-Europeans who thought their homeland was finally on the mend.

"It was really part of that wave of hyphenated Afghans and internationals wanting to come to Afghanistan, post-Taliban, [to] do something, rebuild, reconstruct, that kind of thing," he says.

In a surprising about-face, Afghan President Hamid Karzai appears to be abandoning his government's long-standing effort to hold peace talks with the Taliban in Pakistan, saying they aren't serious about negotiations. NPR's Quil Lawrence reports.

Last week's assassination of the former Afghan president, Burhanuddin Rabbani, not only dashed hopes for peace negotiations, it also increased the talk of civil war.

It came at the time that American troops are preparing to begin a gradual withdrawal from Afghanistan, exposing deep anxiety among Afghans about what lies ahead.

Afghanistan buried a former president last week, but there is concern in Kabul that something else may have been buried as well: the peace process. In nearly two years since the U.S. opened the prospect of negotiations with the Taliban, progress has been hard to discern.

The assassination of Burhanuddin Rabbani, who was also the head of Afghanistan's High Peace Council, may have quashed any negotiations that were under way. It also may have given new strength to those who never supported the idea of talking with the Taliban.
