US mulling Syrian emergency intervention?

[Skybird]

After reports that Syria has started to mix chemicals and produce Sarin, by doing so apparently preparing the use of chemical weapons soon, Obama and his speaker both delivered clear words and warnings of "consequences", apparently wanting them to be understood as an announcement that using chemical weapons would trigger a direct military intervention by the US immediately.

A group of 150 US specialists already has been moved to Jordan earlier this year, to help both with refugee movements, intel and preparing the Jordanians for a possible chemical use in Syria.

Syria has practiced and live-fired chemical artillery shells already earlier this year and in the presence of high military commanders from Iran.

I assume war-tired Americans do not like the prospect of just another war to embark on, with a later war against Iran also within possible reach. I sympathise with that attitude.
