OP: Yes, I think the UK will intervene in some way.
No, I don't think we should, a look back through history shows this has led to huge numbers of deaths on all sides together with increasing unpopularity for the UK - coupled with little or no resolution for the country the subject of the intervention. We go, and then pull out leaving a bitter, bloody mess than festers on for decades.
Further, we did nothing about Pol Pot, the Rwandan massacres, or the continuing unrest in Southern Africa - I'm sure those better versed in current affairs can point to many other conflicts where we have looked the other way. Why so fired up about Syria?
But mainly for the reason that this country hasn't got any money. Hospitals, police and fire stations are being closed, legal aid funding slashed, cut-backs in services for those who are long-term unwell. Put simply: we can't afford it.
China is well resourced, and has a great deal of influence, let them get involved (ok, on a side we consider to be the "wrong" side), let them spunk millions of yen on bullets and bombs and lose hundreds, if not thousands, of their own people.
Just my opinion.
