All of it is nonsense. The US has supported terrorist coups in the middle east (and other areas) for over 100 years at this point. We, as a country don't have anything to worry about because we ARE the terrorists. Until some stronger nations rise above our economic prowess, anyway. Both of these countries are full of good, hardworking people who just want to live independently, and they are being occupied by violent hostile troops who have killed over 206,000 non-combatant citizens, destroyed schools, homes, etc. There never was a viable terrorist threat in these countries. If we wanted to end terrorism, we would stop being terrorists (or funding it) ourselves. In any case, I would only suppose that Afghanistan poses a larger threat to US troops merely because we have slightly less troops funneled there as opposed to Iraq; to directly answer your question.
