WASHINGTON -- In December 2009, our commander in chief went to West Point and proclaimed that he would withdraw all U.S. forces from Afghanistan by 2014. Since then, he has proudly emphasized that "We are on a course to end this war responsibly." Now U.S. and NATO troops and loyal Afghan soldiers and police officers are reaping the bitter harvest of the seeds that Barack Obama planted with those words.

Over the last 10 days, in five separate incidents, seven American military personnel were killed in what used to be called "green on blue attacks" -- where Afghan soldiers or police have assaulted their U.S. and NATO counterparts. Thus far this year, 37 coalition troops and civilians have been killed in 29 incidents of what the Pentagon now calls "insider attacks." According to figures released by the NATO command in Kabul, there were 11 such events in all last year, resulting in 20 deaths.

Until now, the Pentagon and NATO command in Kabul have maintained that these "sporadic incidents" were usually the consequence of "personal grievances" and "related to people getting into arguments." In March, after an insider attack that killed two British commandos, Defense Secretary Leon Panetta said the assaults by individuals wearing Afghan police or military uniforms weren't part of "any kind of broad pattern of activity." That perception has been altered by events on the ground in Afghanistan.

On Tuesday, following two attacks perpetrated by Afghan nationals that resulted in six Marines killed and two wounded, U.S. Gen. James Amos, Marine Corps commandant, took the unusual step of issuing guidance to all U.S. Marine leaders. Amos, it should be recalled by my media colleagues, co-authored the "Counterinsurgency Manual" with Gen. David Petraeus; it was used as the guidebook for the fight in Afghanistan. In his letter dated Aug. 14, 2012, Amos notes that the recent assaults "were carefully crafted to drive a wedge between us and our Afghan partners." Importantly, he also warned his Marines: "More of these types of spectacular attacks can be expected..."

A day after the Amos message went out, Panetta and Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, acknowledged at least partial reality in a Pentagon press conference. They now say the Taliban is "resorting to these kinds of attacks to create havoc." But in that same press conference, Panetta, perhaps forgetting this is not a conventional war, claimed that "the Taliban has not been able to regain any territory lost..."
