In terms of Afghanistan. . . .
It's good to see that there is now a more acknowledged recognition that achieving solutions / stability also involves economic, political and social dimensions (something along the lines of what was once, I believed, called a "hearts and minds" strategy).
It's like also good that there now seems to be a more widely accepted understanding that the Taliban is not a monolithic structure - that all Taliban are not international Jihadist. It's good to see an admitted understanding that many Taliban members and groups are far more concerned with local, family, and tribal affairs than they are with larger "global" issues.
That these new perspectives will bear fruit remains to be seen - seems like a long shot at best, but it does seem a better shot that we had previously.
But no solution to Afghanistan lies solely within that country's borders. And the external dimensions of the solution are at least as challenging and daunting as are the internal ones. What's to be done with Pakistan - what can be done with Pakistan? What can be done about relations with Pakistan and India and the Kashmir? Absent an resolution in Kashmir, it doesn't possible to wean the Pakistani government away from support of Jihadist groups including the Taliban.
I had not until recently had any understanding of how the Kashmir situation influences Pakistan's policies towards Afghanistan. If what I'm learning is somewhat true, then "fixing" Afghanistan will be far more difficult than I had ever imagined. I've no clue if achieving stability in Afghanistan is possible - it seems to me that we have to try. And, I hope we do and that we achieve some measure of success. But, absent regional solutions I don't know that success within Afghanistan is possible.
