Time to take out President Assad's weapons of mass destruction

So now we know for sure. Not only does Syrian President Assad have weapons of mass destruction,  but he has threatened to use them against so called 'external enemies'.
With the regime in slow decay,  and defections now happening daily,  the Baathists now realise that their only hope of remaining in power is to utilise its chemical weapon arsenal.
'External enemies' could mean anyone: Israel who shares a border with Syria,  Kurdistan in northern Iraq (their are millions of Kurds inside Syria),  or even Turkey which has become a de facto safe haven for some of the Assadist opposition.
One thing is certain: condemnation and sanctions are no longer enough.  The West - through Nato -  should take preventative action, take out the Regime's chemical weapon arsenal - before it is too late.
P. S.  Under the UN doctrine 'Responsibility to Protect' , adopted by the General Assembly and Security Council,  preventative action is justified under international law in order to stop mass genocide.
