There is no doubt that the “White Helmets” is a British funded group. That is well known. Their leader was refused entry into the United States and 65 of their “members” we’re identified via social media as being ISIS. They stopped publicising their membership after that happened.

White Helmets are part of Al Nusra, a fundamentalist Sunni Salafist jihadist group.
Which is why their leader was refused entry to the United States.
They are not neutral in the Civil War, but are a very good front for getting contributions from Hollywood types.
