The shells containing the gas came from the air. Only Assad and Russia have airpower in the area. Bombing raids are tracked by satellite. Both airforces were raiding the area forcing civilians to take shelter in the basements of their buildings. Two helicopters were seen flying low before the shells were dropped.
The Russians blocked the UN resolution calling for an investigation.
To counter these facts, the best that Putin/Assad apologists can come up with is 'Why would they? No motive'. Just as they did with the Skripals. Followed on by denial that the attack took place, because all they've seen is pictures in the press of men with hoses and children with oxygen masks.
Don't they realise that there are piles of graphic photos on the picture desks of media outlets that are too gruesome to print? Susie Boniface from the Mirror described these photos on Sky's press preview.
If NATO were doing this, Stop the War would be all over it. Marches and demonstrations. It's been going on for 7 years. 1,000 died in the last gas attack. But not a peep from the usual suspects. The wrong sort of war?
I don't know what should be done - apart from the fact that it's time Congress got its act together and the men in white coats came and took Trump away. Whatever we do, it's too little, too late. Obama shouldn't have let them cross his red line 5 years ago. Some MPs are already regretting the way they voted.
International law on the use of poisonous gas in warfare is too precious to be ignored with a shrug. 'Because of Iraq'. On this, I agree with Blair. 'Doing nothing has consequences.'
