New U.S. intelligence assessments say the war in Afghanistan cannot be won unless Pakistan roots out militants on its side of the border, which it's still unwilling to do.

That's according to U.S. officials who've been briefed on the reports.

But U.S. military commanders caution that the gloomy National Intelligence Estimates for Afghanistan and Pakistan are based on outdated information that does not take into account progress from an increase in security and a crackdown on militants this fall.

The officials spoke on condition of anonymity to discuss the classified documents.

The reports may overshadow positive trends that military commanders are emphasizing before a White House review of the war due next week.
