The western countries are embarking on smearing campaign again.

If we use our common logic, we will know that there is no valid reason for President Assad to use chemical weapons to attack its people because Assad is winning the war in Syria with Russian's help.  Furthermore, the USA was planning to pull out of Syria as it was losing the Syria war against Putin.

I believe President Assad can wait for the USA to pull out first before taking over the whole Syria.  There is really no reason for Assad to embark on a chemical warfare.  Thus, this is another smearing plot by the USA to give it a legitimate reason to attack Syria with UK & France.

We are seeing the same Iraqi situation in Syria now.  The culprits behind this are US, UK & France.
