We can probably manage to secure our single identifiable current objective for Afghanistan with even fewer resources than we have there now. However, recent events have taken a(n ironic) turn that suggests it might be worth ramping up our presence there, at least for the short term.

For a combination of reasons, Pakistan finally seems to have discovered sufficient motivation to mount what appears to be a serious (if probably short-lived) campaign against the Taliban presence there. To the extent that the opportunity isn't already past, it would be of some benefit to have at least some of the enemies assets between a rock and a hard place while the planets of Pakistani military and Pakistani public opinion are still somewhat in alignment.

So maybe there is a possibility of achieving something slightly more than an occasional remote-control assassination with accompanying collateral damage.
