In my point of view the last message of Bush to Iranian people was positive and not black and white as it used to be, to describe Iran as axis of evil and may be it would be helpful to find a diplomatic solution for this nuclear crises.
"My thoughts and prayers are with the Iranian people, particularly the families of the many Iranians who are in prison today for daring to express their hopes and dreams for a better future. We continue to stand with the people of Iran in your quest for freedom, prosperity, honest and effective government, judicial due process and the rule of law. And we continue to call on the government of Iran to respect the will of its people and be accountable to them.
As I have said before, if Iran respects its international obligations and embraces freedom and tolerance, it will have no better friend than the United States of America.
Best wishes for a bright future, filled with knowledge and information and freedom."
