Eclectic: I'm afraid you are far to gung ho for your own good and I might even say very one sided with an axe to grind. If, as other posters have stated and I agree with them, that if you feel so strongly about the situation, your flight could be leaving from Birmingham or Heathrow soon. It appears you have a desire for military intervention but I suspect that you will not be part of a UK response, just shouting from the sidelines unlike others who will actually push the release button.
To come back to the main point of the suspected agent being Sarin, I refer you to the report from the Guardia/Observer today:
Syrian hospitals treated thousands for poison gas symptoms, says charity | World news | theguardian.com
The potency of the agent released appears very low with a 10% mortality rather 85 - 90% you would expect with Sarin. This leads me to believe that this is 'bath tub Sarin' rather than industrially made.
As to intelligence available and stating that the decision has already been taken, in the UK, as it is not an emerging danger to the UK Parliament will have to be recalled and the situation debated and voted on. the perils of democracy mean we cannot just attack in this situation.
You also assert that Cyprus is an unsinkable aircraft carrier, which is true, but I suspect the Jordanians would be unhappy to be seen as such and your laughable conspiracy theory that Israel that would allow bases to be used is patent nonsense and will not allow SLCMs to overfly their territory. The Israeli's will just sit behind their border and let everyone kill each other, less of a problem for them and a politically neutral stance.
Eclectic, as I stated at the start, your flight leaves soon from an airport near you, go and join the fight, as if you go it may mean one less UK/US serviceman/woman who has no choice in going, or are you either a troll or a keyboard warrior who unlike many on here like myself served in HM forces. We should stay out and only help the refugees in Turkey and Jordan. NO NO NO to any involvement.
