Well I don't understand the conflict, but I am 100% sure it is not as simple as the BBC etc would like to make out.
(I.e. Bashir al-Assad is an evil dictator who likes to kill his people...)
I think Russia and China are right to force the UN to hold back. The problem should be solved by the Syrians themselves, without meddling by anyone. But as usual, certain countries can't keep their hands off but keep inflaming the situation.
As I understand, Syria is quite a mixed country with both Moslems and Christians, as well as different peoples and languages. There are millions of refugees from both Iraq (recently) and Palestine who have resettled there in a sort of permanent exile.
Up until now all the different groups have been living peacefully, respecting each other, with the rights of minorities protected.
My interpretation of the situation is that there was unhappiness with the government there, inspired by the Arab Spring. Certain Western powers which have wanted to oust the current Syrian government for decades, ceased the opportunity and did everything it could to stir up the rebels, arm them and launch a media campaign to support them. How legitimate the complaints of the rebels are, I would not know - but al-Assad is definitely no Saddam Hussein, he is/was genuinely liked by many and has in fact tried hard to improve the country although his rule is probably not without faults.
Don't know, this is too complicated for me. But taking down the regime in Syria has been on the US war "roadmap" for a decade according to many sources, for example General Wesley Clark.

I expect they have a "good" reason for wanting to do this, and these reasons normally have to do with oil, don't they....
I read that Homs is a very religious (moslem) city. The people there are traditionalist.
