"Did those here who oppose Obama's proposed intervention, object to him promising to act against the use of chemical weapons at the time?
Did they post here describing it as warmongering?
Stringsinger?"

Keith, no one here condones the use of chemical weapons. The issue is that the way to achieve success is not through warmongering but diplomacy. This is Obama's best action.

Now the question here is often referred to as a "conspiracy theory", a term that originated with the CIA to discredit anyone who questions the validity of some news reports.
Usually, the conspiracy theorist is not dogmatic as suggested but is merely asking for a reasonable conclusion that makes more sense such as why did Number 7 Tower come down on 911.

Is it possible that the CIA did plant sarin to achieve a political objective? Given the history of the CIA and MI6 it is a reasonable question to be asked.

"Incident 1: Tokyo subway attack at the height of the Tokyo rush hour where five separate trains were attacked some extremely well educated and intelligent "nutters" who manufactured their own Sarin managed to kill 13 people."

This may or may not be associated with attacks on Damascus.

"Incident 2: The attacks in Damascus on the 21st August 2013 killed 1429"

This figure has never been established to be accurate. Some say more, some less.

"Incident 3: In Iraq Saddam Hussein killed over 5,000 in one single attack in 1988"

Yes but was it sarin gas? Again a different incident and not related necessarily.

"The difference? In Tokyo the agent was home made, in Syria and in Iraq the agent was professionally manufactured, weaponised and delivered by a dedicated means purposely designed to cause the maximum amount of death and incapacity."

And what major countries in the world would be capable of this manufacture and its delivery? And how do you know which one?

To announce such an authoritative description and analysis would mean that the person in-the-know would have to be connected to an undercover agency such as the CIA otherwise this is just conjecture not based on known evidence.
