I would have gone in, but only to bomb them back to the stone age they love and to decimate their damn poppy fields.
We “won” in Afghanistan in the first 6 weeks - it a was brilliant effort - but we left the tribal leaders in power.
Even now, today, if we resolved to torch every poppy field we’d rob the war lords of their power. Not really hard to find the fields between the miles of rocks and dirt.
The fact that we haven’t means we are not in it to win it.
