Brother, Baloch issue is very different from that of Syrian issue. Baloch rebels want to dismember Pakistan further. In contrast, Syrian 'revolutionists' want change within their country and Assad to go. These guys are part of common people in Syria.
When protests started in Syria, they were initially peaceful. It is possible that some voilent incidents may have taken place but this happens in many countries. What Assad did in response is that he ordered the military to shoot the protesters to force them to abandon their calls for change. And this is why many Syrians fled their country to save their lives but some decided to fight back. And now they are being labelled as terrorists by Assad and his supporters. What nonsense is this? Several months have passed by now and people are still protesting in Syria. Something is not right, correct?
This would have remained internal issue of Syria if refugee crises would not have happened. However, thanks to brutality of Assad - his actions have brought international attention.
Let me make this clear to you - when it comes to interests, Russia and China are no saints either. Both of these nations would support brutal dictators too when it suits their interests. Difference is that USA is more aggressive in its foreign policy matters.
