i was just reading an august issue of newsweek and i found this very interesting line...
america loves imposing sanctions on governments it deems dangerous. the problem is, they don't work. witness the 45-year-old embargo against cuba and the 57-year injunction on north korea. sanctions rarely help oust regimes, and only further isolate opressed populations-who might someday stage a coup-from the influence and aid of the outside world. washington might as well say,"hey power to you Ahmadinejad".
