Mattis' new Afghanistan strategy includes putting pressure on Pakistan, source says: 

In his public statements before four congressional committees, Mattis promised to correct the mistakes of the Obama administration, in particular by backing up beleaguered Afghan government troops by restoring robust NATO air support for ground operations against the Taliban.
"The revised Afghanistan strategy with a new approach will be presented to the president for his approval in the coming weeks," Mattis said.
