With respect - these are not your garden weed type jihadis. They don’t go out, planting IEDs and waving AK’s in the air.
They are the ones that send others. They don’t need to be physically present to cause damage. Right now, the only thing stopping them from getting back into the battle is they are out of the loop as far as forces, cells and newer tactics are concerned, and they will be viewed with suspicion by the current leadership, in case one of them has been turned by the USA. The Talis and AQ didn’t get to be threats by being as trusting as Shirley Temple. They’ll be watched for a bit.
But these guys are heroes to their troops...and they are ready for some payback.
