Second time's the charm?

Here: MacKay sees risks in U.S. plan to arm tribal militias [in Afghanistan].

Isn't this the most delightfully and tragically ironic plan? In the 80s the USSR armed the Afghan national army to take care of the mujahideen.

So let's arm them some more, because it worked out really well last time.
