It's hard to tell but the US might be worried that the perception of Obama is that of a peace-maker/diplomat as opposed to Bush & the administration might fear a more aggresive Iran. Obama has also publicly stated that he favours diplomacy with regard to Iran's nuclear programme. In my opinion this gives the green light for Iran to pursue the bomb [I would not be surprised if Iran already had one viable device]. Note the difficulties the 'coalition forces' are having in Afghanistan. The West are struggling to defeat the Taliban in Helman province in particular despite their superior fire-power. With weakening economies both UK and US are planning to withdraw soon from Iraq and both are struggling to finance these wars against terror [hence their massive debts]. Once out of Iraq, the situation there will be interesting - a pro-Iranian or an Iranian sponsored group might come into power and hence you will have a powerful Muslim bloc [with vast oil resources and revenue!], which could sponsor a nuclear terrorist attack on New York and Rome, thus weakening the economies of the West further leading to massive unemployment, even food shortages leading to civil unrest and civil disorder. Things are changing more quickly than we could ever have imagined even 10 years ago. Garabandal
