It was totally against his policy in not interfering in Muslims killing Muslims, the purpose of the attack was a warning to Bashar and not really meant to cause a lot of damage..I am not a fan of the guy but then the worst western leader has more empathy than the best we have. Look at that rat King of Saudia traveling with 500 tonnes of cargo and a gold escalator. It is widely accepted that the attack was based on emotional response to pictures of dead babies.
Didn’t they also blow up dozens of children in a bomb on school buses in Syria, western people will not purposely target babies.
