The President of Iran, Mahmoud Ahmadinejad, accused the USA of they forge documents that supposedly would indicate that the government from Teheran would be working to get an important component for the production of a nuclear bomb. In an interview to the net of North American television ABC, Ahmadinejad affirmed that documents published in the week passed by the British newspaper The Times, that it describe a plane assumption of Iran to test a device that works as a "nuclear trigger", would have been manufactured by the government from the USA.
Considering the recent history of the USA, the President of Iran deserves more credibility than the White House. After all, "los gringos" invented proofs to invade Iraq in order to control the income of the petroleum of that country. I don't doubt that "los gringos" are capable to do the same to attack Iran.
Unhappily, in reason of the growing aggressiveness of the USA now the only countries that can be calm are those that it doesn't have petroleum or that has many atomic bombs.
