This is as serious as it gets:
From the BBC News above:
Russia and China have stepped up their warnings against military intervention in Syria, with Moscow saying any such action would have "catastrophic consequences" for the region.Attacking Syria with cruise missiles would be pure insanity. It could easily result in a massive war in the middle east with unpredictable consequences that could draw in Iran and even Russia.
As for the chemical attack, it is hard to believe that the Assad regime really used such weapons. Assad has been winning using conventional weapons. As brutal as his regime is, they are not suicidal. They only ones who had a real motive to use chemical weapons were the rebels, to provoke an intervention, as they seem to be losing the war.
We need to stay out of Syria.
