TFG asked: Have you noticed that Obama has broken (another) promise? During his campaign he said that his first trip to Canada he would tell them how he would change NAFTA. Now he is saying nothing will change to NAFTA. Do you remember when he campaigned differently?

Hilts asked: Eggcatcher asked a question about U.S citizens visiting Cuba, and they cannot. Would there be a problem for, say U.K citizens visiting Cuba then wishing to visit the U.S? There used to be a problem getting into Greece if you had been to Turkey.
