President Barack Obama won''t accept any of the Afghanistan war options before him without changes, a senior administration official said, as concerns soar over the ability of the Afghan government to secure its own country one day.

Obama''s stance comes as his own ambassador in Afghanistan, Karl Eikenberry, is voicing strong dissent about a U.S. troop increase, according to a second administration official.

Eikenberry''s misgivings center on a concern that bolstering the American presence in Afghanistan could make the country more reliant on the U.S., not less. He expressed them in forcefully worded cables to Washington just ahead of Obama''s latest war meeting Wednesday.

The officials spoke on condition of anonymity to discuss administration deliberations.

The developments underscore U.S. skepticism about the leadership of Afghan President Hamid Karzai, whose government has been dogged by corruption. The emerging administration message is that Obama will not do anything to lock in an open-ended U.S. commitment.
