The US is guided by a financial timeframe in Iraq. Unfortunately they will have to cut their loses and get out. If Iran starts to thumb their noses as they have allready started to do to the west, US may be provoked to start a fight that may be debatable of a guaranteed win between the stupid Iranian government and the most powerful nation on earth the US. So what is the US to do in the event of such scenario? The US must seriously redefine its foreign policy as well it must clearly define its objectives for its presence in countries which is not welcome in. If some one says to some one you are not welcome in to my home, the guest must not take a gun and force his or her way in. Simple as that. The next twenty years are going to be the most difficult years on this planet, because this century is about wealth against religion, and communism against imperialism. North Korea would love to get the US bent out of shape so would the idiot Mahmoud Ahmadinejad the Iranian goof that thinks that Iran will be the Power Broker of the Middle East. These two despicable sorry examples of human life are the real threat against world peace. So, the US it may be the most powerful nation on the planet, but there is some trouble facing the West, especially when we see the idiot Iranian President Mahmoud Ahmadinejad just visited Venezuela looking for friends to gang up with against the US.
