I believe Ahmadinejad believes it

Some Middle East observers believe Iranian President Mahmoud Ahmadinejad's letter to President Bush could be a precursor to war, based on a traditional Muslim pattern of offering acceptance of Islam before establishing it by force.
It's been observed for a few years and I think this is one of the reasons Bush did not want one on one talks with Iran.
