I would say that this is a sign that its past time to leave and let the Afghans stew in their own hatred.

Suspected insurgents opened fire on Tuesday on senior Afghan investigators of the massacre of 16 civilians by a lone U.S. soldier, Afghan officials said, just hours after the Taliban threatened to behead American troops to avenge the killings.

The gunmen shot from long range at two of President Hamid Karzai's brothers, Shah Wali Karzai and Abdul Qayum Karzai, and security officials at the site of the massacre in Kandahar's Panjwai district.

Karzai's brothers were unharmed in the brief battle, which began during meetings with local people at a mosque near Najiban and Alekozai villages, but a soldier was killed and a civilian wounded. The area is a Taliban stronghold and a supply route.

The Taliban had earlier threatened reprisals for the weekend shooting spree, which came weeks after deadly riots across the country over the burning of copies of the Koran by U.S. troops at NATO's main base in the country. That violence led to calls to accelerate a 2014 goal for the exit of most foreign combat troops.

"The Islamic Emirate once again warns the American animals that the mujahideen will avenge them, and with the help of Allah will kill and behead your sadistic murderous soldiers," Taliban spokesman Zabihullah Mujahid said in a statement, using the term by which the Islamist group describes itself.

The grim warning, which was unlikely to have any impact on heavily-protected NATO soldiers on the ground, followed the February beheading of four Afghan men by insurgents in a country where such killings are relatively rare.

Please examine that last statement by the Reuters reporter. Beheadings are "relatively rare." Relative to what? London? Paris? Even Baghdad? In other words, Afghanistan isn't quite the 7th century backwater we've been led to believe?

Three cheers for that.

Meanwhile, they don't want us there. We don't want to be there. And only the Taliban thinks we should be there so they can kill more of us.

Maybe we can build a fence around the entire region and keep the contagion of madness confined to Pakistan and Afghanistan.
