The Taliban may be able to increase the number of incidents and casualties, but this doesn't mean they are winning. I wrote much the same about the war in Iraq. Our side's power increases more rapidly than they can mobilize their power, and the killing the enemy does manage to carry out--because it isn't on a grand enough scale to intimidate given our presence and effectiveness--just angers the civilians who have to decide who to support. Strategypage has an interesting overview of the fight.
The Taliban pulled off another atrocity by killing ten Afghans:
"It was a suicide bomber who detonated a motorcycle as an Afghan National Army (ANA) vehicle was passing by," Daud Ahmadi, spokesman for the Helmand provincial government, told AFP.
"The blast killed ten civilians and injured seven others," he said, adding that it took place around 1.45 pm (0915 GMT) in the Gereshk district of Helmand, a cauldron of Taliban insurgent activity.
The blast struck a bridge in the Bughra-pul area of Gereshk, on the main highway between capital Kabul and Herat, Afghanistan's second city, he said.
Beneath the bridge, crowds had gathered on the banks of a stream to mark Nowruz, the Zoroastrian new year which falls on the March 21 equinox.
And thus the "resurgent" Taliban continue to lose battles and hearts and minds.
