You americans want everything.You are selfish.The terrorism has grown because of your invasion.You are blind,because you don't see that more and more people hate you.A lot of countries turn against you.Your politics are very aggressive and not friendly.If you will invade Iran ,I don't think you will get out from there with your army in one piece.The terrorism in Iran is because of you.They associate you with the Europe, so they want to kill europeans too.If you go in Iran ,it will be like in Vietnam.So you can not have the world for you.In the end you will fall like the roman empire.
