The group was created with the help of Purpose Inc, a U.S. company specialized in regime change NGO operations. Purpose Inc is also behind Avaaz which early on peddled fake war on Syria video propaganda. The White Helmets are financed, like all „Free Syrian Army“ media propaganda, by USAID with some $23 million and by the UK Foreign Office with a total of some £23 million. The Netherlands and Japan also donated money to the scheme. The group was build up and trained since mid 2013 by a „former“ UK military intelligence operator residing in Abu Dhabi. These are propaganda artists camouflaged as humanitarians.
The „White Helmets“ cooperate closely with al-Qaeda. One of its leaders was recently denied an entry visa to the United States. More details about the group researched by Vanessa Beeley can be found here and here.
