President Ahmadinejad of Iran has denied the charges that his government supports Taliban insurgents.
Prior to Ahmadinejad's coming to power, while the U.S. planned the invasion of Afghanistan, Iran helped organize the Northern Alliance against the Taliban. Though the U.S. has downplayed Iran's role in the early days of the war, U.S.soldiers and officials have conceded that Iranian forces were present with the Afghan rebels in 2001. In his 2006 article, "How Neocons Sabotaged Iran's Help on al-Qaeda" author Gareth Porter wrote:
"After the Sept. 11 attacks, U.S. officials responsible for preparing for war in Afghanistan needed Iran's help to unseat the Taliban and establish a stable government in Kabul. Iran had organized resistance by the Northern Alliance and had provided arms and funding at a time when the United States had been unwilling to do so."
The article quotes Flynt Leverett-- senior director for Middle East affairs in the National Security Council at the time-- who said that State Department and NSC officials met secretly with Iranian diplomats in October, 2001 to discuss "how to effectively unseat the Taliban and once the Taliban was gone, how to stand up an Afghan government."
The State Department's policy planning staff wrote a paper in November 2001 recommending that the U.S. pursue more formal cooperation with Iran in fighting al-Qaeda. Yet collaboration with Iran in Afghanistan would have involved equal sharing of information about al-Qaeda between the two countries, and since the Bush administration had already decided to include Iran on its "axis of evil" hit-list by then, the U.S. turned its back on the idea.
As Neocons use the WikiLeaks story of Iranian efforts to hamper the U.S. occupation of its neighbor in order to push their agenda, no doubt they will overlook the fact that in 2007 the CIA received presidential approval to mount a covert operation to destabilize Iran's government. It's even less likely that they'll mention that Iran's democratically elected government was overthrown by the CIA and replaced by the heavy-handed Shah-- a U.S. puppet-- when it wanted to nationalize its oil fields back in 1953.
Such facts aren't convenient for a U.S. government trying to seize the moral high ground while biding its time for the right moment to launch another unprovoked attack on a sovereign nation. WikiLeaks documents-- disinformation or not-- are being used for anti-Iran propaganda, OpEdNews
 Mr. Obama first made waves with his views on Iran policy in 2007, when he said during a Democratic debate that he would, as president, be willing to meet without preconditions with Iran's leaders, and that the notion of not talking to one's foes was "ridiculous."
Since becoming president, Mr. Obama has pursued diplomacy, but his stance has become steadily more confrontational. Iran's Nuclear Program, The New York Times
Speculation by bloggers, including John Young of Cryptome.com, and an expose at The Intel Hub that the WikiLeaks is part of a disinformation operation, and that the documents themselves could even be fake, should put every left leaning American on Yellow alert.
