In a briefing to the U.N. Security Council Wednesday, the Norwegian official said the allies' mission will fail if Afghan civilian institutions are not strengthened, The Washington Post reported.
"What we need is a strategy that is politically and not militarily driven," said Eide, who will step down from his job in March. "If we do not take these civilian components of the transition strategy as seriously as the military component, then we will fail."
Eide's comments come ahead of the important Jan. 18 international conference in London that will focus on Afghanistan.
In Kabul, President Hamid Karzai, under pressure from his Western allies to root out corruption in his government, needs to form a new government after parliament last week rejected 17 of the 24 Cabinet nominees he had submitted in his first list.
Eide urged better salaries for Afghan government administrators and called for a reconciliation process that would include Taliban insurgents who give up violence, the report said.
Later Rosemary A. DiCarlo, the U.S. representative for special political affairs, said the administration of U.S. President Barack Obama is committed to increasing civilian participation in the Afghanistan transition, the Post reported. She said the United States plans to triple its civilian presence there to about 1,000 as it prepares to send an additional 30,000 troops and that the administration has supported integration of Taliban insurgents who lay down their weapons.
Eide also listed among his worries declining public support in the West for the Afghan effort and the Western allies' failure to counter the Taliban insurgency.
