Syria

After the rioting last summer imagine that a politically or religiously motivated group had managed to obtain some basic weaponry, declared itself as the 'Free British Army' and occupied areas of our cities.
What would our government have done?
Well, they would probably have mounted a robust police operation to end the occupation and bring the perpetrators to justice. If the police could not do it then it would seem logical to involve the army in joint operation.
Any such occupation or uprising would be termed as a series of criminal acts and I guess that public opinion would be on the government side except in the occupied areas, where it may be safer and more expedient to support the 'Free British Army' (FBA).
I also think that the government would not be particularly receptive to calls to talk with the FBA from other countries thousands of miles away with a very different cultural perspective. They would be outraged at offers to support, train or arm  the FBA from these countries.

Yet we, and others, are doing exactly this to Syria. To greater or lesser extent we did this to countries involved in the Arab Spring uprisings, notably in Libya where western powers actually won the war for the revolutionaries. Yet in no instance have the old regimes been replaced by real democratic systems and in most cases the countries are sliding toward of position of Islamic enmity rather than secular democracy. I cannot understand why the west would want to topple Syria into Islamic extremism, which is what will happen.

Syria is certainly not a country with a record of good relations with the West and has a poor record in respect of human rights and political freedoms. It is however a secular society with a significant christian minority (9%).
If Syria was to fall, bearing in mind the attitude to non-muslims now predominating in counties that were involved in the Arab spring, what would happen to them?
