As a member deployed on Roto 5 I can't speak for the rest of Afghanistan, but it Kandahar they're about back to where they were in 2006 from what I see, a little weaker but also a little wiser. We're pretty much where we were two years ago really, with some gains and some losses. I'd call it a stalemate overall. As winter approaches Roto 6 taking over from us is inevitably going to roll them back but overall here they've had a decent summer, and all else remaining the same we'd probably be back where we started next summer.
What'll change the situation is the steady increase in US forces. That gives us the ability to expand our footprint and push into new areas. 2-2 Inf moved into Maywand earlier this month, which is a longstanding Taliban "logistics node" where most of the weapons, drugs and fighters smuggled into Zhari/Panjwayi and Northern Helmand come through. Until now we've never been able to affect it - neither us or the Brits had the numbers to keep a permanent and powerful presence there. I'm expecting good things from 2-2.
As more and more US forces arrive the Taliban are going to lose more and more safehavens. At the same time they *are* getting better tactically - some of the guys in 2 PPCLI were here for MEDUSA and said after one battle in Siah Choy that the enemy there was a lot better than what they fought in 2006 - more aggressive and more tactically savvy. So as the Taliban start to lose key terrain they're going to get nasty, which could mean some hard fighting ahead. What will ultimately decide this though is the fact that the Taliban have *nothing* to offer the populace. When we move into areas the Taliban have held for *years* there is no loyalty to them on the part of the locals - if we can provide security and services, then they're all for us and its as if the Taliban had never been. Look at the fall of Musa Qala in Helmand. Even with the corrosive effects of Government corruption and mismanagement, the Taliban are still an entirely negative movement that relies on our absence to coerce and threaten the populace, and has nothing positive to offer over event the most meager efforts of Karzai's henchmen.
