Perhaps a salutary message to North Korea and its missile programme. The problem here was Obama threatening about red lines and doing nothing! Don't threaten unless you are prepared to see it through, it makes you look weak and indecisive which is exactly how Russia perceives the West, the US in particular. Huffing and puffing about Crimea, Ukraine and until now Syria. The UN can do nothing as Russia and China always use their veto unless it suits them otherwise, making the UN helpless in the face of of appalling aggression. You simply cannot stand by wringing your hands and watch while innocent people are killed in such an appalling way, it just can't be done, someone has to make a stand and tell these vile people that this method of warfare will not, cannot be tolerated! Even in WW1 mustard gas, the results of which although only mild, I witnessed first hand, was viewed with horror on all sides which led to its being banned.
