do you think the world can realistically move off its addiction to oil and gasoline in the next 20 years? let me know what you think. some exciting news. we have received countless requests from you for an audio version of the "gps" podcast. the video file is too big, you said, you wanted to listen to it on your ipod, your car stereo, et cetera. we heard you, and we've done it. you can now subscribe to either the audio or video podcast at itunes. and you can always see either version on our website, cnn.com/gps. all this is free. now, as i do every week, i want to recommend a book. i find that there's usually very little new to say about the middle east. but the author steven kinsler has found something quite novel and interesting to say in his new book "reset: iran, turkey, and america's future." he recommends that the united states find new partners in the region, that saudi arabia and israel aren't cutting it anymore.
