WHEN people in Washington talk about shrinking the drone program, as President Obama promised to do last week, they are mostly concerned with placating Pakistan, where members of the newly elected government have vowed to end violations of the country’s sovereignty. But the drone war is alive and well in the remote corners of Pakistan where the strikes have caused the greatest and most lasting damage.

Drone strikes like Wednesday’s, in Waziristan, are destroying already weak tribal structures and throwing communities into disarray throughout Pakistan’s tribal belt along the border with Afghanistan. The chaos and rage they produce endangers the Pakistani government and fuels anti-Americanism. And the damage isn’t limited to Pakistan. Similar destruction is occurring in other traditional tribal societies like Afghanistan, Somalia and Yemen. The tribes on the periphery of these nations have long struggled for more autonomy from the central government, first under colonial rule and later against the modern state. The global war on terror has intensified that conflict.

These tribal societies are organized into clans defined by common descent; they maintain stability through similar structures of authority; and they have defined codes of honor revolving around hospitality to guests and revenge against enemies.

In recent decades, these societies have undergone huge disruptions as the traditional leadership has come under attack by violent groups like the Taliban, Al Qaeda in the Arabian Peninsula and Somalia’s Al Shabab, not to mention full-scale military invasions. America has deployed drones into these power vacuums, causing ferocious backlashes against central governments while destroying any positive image of the United States that may have once existed.
