Tough decision for POTUS to make, here is a quote that might offer some insight...

“The amazing thing about it is there’s no complaints from McChrystal or his staff about the administration on any substantive ground. After all, McChrystal and his allies won the argument within the White House. All the criticisms — of Eikenberry, of Jones, of Holbrooke, of Biden — are actually just immature and arrogant snipes at how annoying Team America (what, apparently, McChrystal’s crew calls itself) finds them. This is not mission-first, to say the least.”
