One of our family friends is a young sunni Pakistani who just joined the Canadian army, and knows he is likely to be deployed to Afghanistan to fight against the Taliban.
His wife apparently was a major influence in that. She is an Afghan Shia, who had family that were persecuted and even killed by the Taliban when they took over Mazar-i-Sharif, and wants her husband to play a role in preventing them from returning to power and repeatign their earlier performance.
