Proving his hatred of the US time and time again.
When zawahri wanted to give an order to his jihadis, he posed with his weapon and published the image. The order depended on which side it was on and where it was facing, the position of his hands and fingers on or off, what accessories were attached or removed, whether the muzzle was pointed up or down...you get it.
This looks very much like those images...a message to those who can read them when WE can’t. Like speaking English to us and arab to muslims.
He is pi$$ed at Britain. He is pi$$ed at us. This is a message and it could be to muslims overseas or possibly to his black troops here. Watch and see what happens after this image circulates. It’s an ‘official’ image so it will be seen worldwide.
