Without Iran the west "cannot win" the war in Afhganistan.

The stark message was issued by NATO Chief Jaap de Hoop Scheffer in Brussels on 27 January 2009.

NATO chief called on United States to request Iranian help in order to achieve victory in Afghanistan. He warned that unless Iran helps, the west "would lose" in Afghanistan.

He said U.S. needs to be pragmatic and call for Iran's help.

Without Iran's help, the Taliban would win and this would be a "disaster" for Europe and America, warned Mr Scheffer. NATO is in "urgent need" to talk to Iranians and get their help.

U.S. and NATO have been struggeling in Afghanistan for 7 year. Taliban militants are still causing many deaths of American and European soldiers.

Top U.S. Commander also admitted that Iran is needed to beat the extremists in Afghanistan. Chief of Staff Admiral Michael Mullen said US needs to talk to Iranians about Afghanistan. He urged the new US President to engage with Iran.

However, many observers think that it is unlikely that U.S. would bend to Iran until its situation gets more dire in the region.
