Guardian: Reports " Soil samples from Syria chemical attack sent to western agencies..Samples will help intelligence agencies establish whether nerve agent came from store of sarin Assad was supposed to surrender "
Lets Get Real:
The Syrian Regime and Russia will try to make the process outlast the interest of the West in the incident, they understand that the Western population has a short attention span, thus they will argue that the WMD attack was down to the rebels, also they will try to get Trump to understand that Assad could be an ally in the War against Islamic Terrorism. One can only hope that President Trump does not lose interest, he has given the impression of some action, sanctions do no work, and the Russians will block any resolution at the UN. Thus the West might be thinking that the US will take military action in Syria.
