The U.S. and its allies have "no smoking gun" proving Syrian forces uses chemical weapons.
No stores of Sarin at Shayrat found by experts.
The terrorists must have moved the chemicals before the inspection from America ever happened. There are military tactics that are done secretly and they have intelligence and insider including spies to tell them about any possible attack that will be coming in. Thus if I am right the chemical weapons might be moved to somewhere safe or if I am wrong the US have acted on its own accord without clear proof.
If it is fee to end the reign of the bloody regime of Assad I do not mind. Let under any pretext, it will be removed. In fact, if Syria was peace and harmony it would be a rich country. Just Assad held with the support of Russian, and they are not interested in the prosperity of Syria.
Very even right think, but I still hold the view that chemical weapons were available in Assad, and he used it. But the army also reported that they found containers from these Russian-made weapons. So there are a lot of questions and it is exhausted.
