Hitler has Sarin gas in World War II – but would not use it – too evil. Now Bashar Hafez al-Assad, with the backing of Putin, has gassed his own children., Defenceless children.
The reason the US is so twitchy about weapons of mass destruction, is that terrorists could drop a gas bomb on Washington – or Moscow.
This is the red line Gadaffi crossed. How stupid is Assad? Putin has no option, to to cease supporting his regime.
