It was heartbreaking this week to see videos of hundreds of people - men, women and children - in Afghanistan risking their lives trying to get onto a U.S. jet that was moving toward takeoff Some of them continued to try to hang on even as the plane began to ascend. Now there are droves of people - Many of them Americans sleeping in orchards and opium fields, moving from house to house just trying to stay alive. Freedom is a precious commodity, and we still have it here in America, but the events in Afghanistan should remind us that we can't take this freedom for granted.
