Proof needed before any attack on Syria
There appears little doubt that chemical weapons have been used in Syria.
The pictorial evidence is heart-wrenching and indicates somebody has inflicted the most savage brutality on innocent human beings. There is, however, some serious doubt concerning the source of the chemical weapons.
Even the most brutal and stupid dictatorial regime must surely realise that use of such horrendous killing technology would discredit it in world opinion and, if proven, would leave it open to justifiable serious retaliatory action and loss of support from its allies.
