Ryan there are plenty of other sources with credible evidence showing how dubious the white helmets are and also who funds them. Look them up.
Focus on the message, not the messenger.
Why would assad, who is on the verge of victory, use chemical weapons? What has he got to gain?
On the other hand the "rebels' have everything to gain from hoaxing an attack.
Given the tactics Nato have employed in the past to get what they want, setting assad up is right up their alley. Iraq was a set up, Afghanistan, Libya...Syria...All countries of strategic interest for Nato, all went down the same road: a relentless narrative besmirching the respective regimes, instigating unrest by using clever social media campaigns, civil war breaks out, chaos ensues.,,
Only this time things aren't going to plan for Nato in Syria :)
Iraq, Syria and Libya were similar. Strong man dictators and reasonably stable countries where a large % of the population would have led a fairly contented everyday safe life - working, raising families, watching football etc etc. Women generally treated okay, but sure far from perfect, and by no means democracies.
Of course if you wanted free press, political change, were an ethic minority life etc probably not so good.
Afghanistan ruled by Tabilan very very different. A cruel medieval system, barely functioning state. Women buried to their neck and stoned to death (barbaric in the extreme) if they had an ‘affair’, or maybe tried to leave their 80 yr arranged marriage husband. No education for girls.
A fudgeing miserable place. A regime change there was a very good thing, though doubt 15 odd years later much has changed for the millions of rural Afghans. At least place now has a glimmer of hope.
