The only suggestion so far seems to be from a Brit author musing on and on about mustard gas, etc.
The only head of government suggesting NFZ, troops on the ground and more warlike bombast is the P.M. of Britain, David Cameron.
Seems Mr. Cameron received his comeuppance from other heads of state and today backed off his typical rhetoric --- ruling the waves and all that.
'sitting' read the whole article then your opinion of 'some' governments yadding on about WMD just may be enlightened?
