The major change in the war against the Taliban is that they are now sandwiched inbetween Pakistani troops (with US liaisons and drone air strikes). Thus not only are the Taliban hit by ground troops, artillery and aircraft, but also at any time by the drones, the fourth leg of the offensive to decapitate their leadership and demoralize the regular fighters.
On the Afghan side, we are doing the same thing, some of which is unannounced and for good reasons.
Now that the Taliban has fled from Marjah, despite their vows to hold it, they have lost some face. And remember, everyone of their members killed even in the delaying actions, is one less fanatic to fight another day.
The old squeeze play is on, and I expect that you will see some very innovative US/NATO operations in the future. If you read good Vietnam military histories/operational reports, you’ll know what I mean.
Been there.
I pray you’re right - for the sake of those I know and communicate with who are boots on the ground in the area. I hope they soon see this happening.
