I think Syria is not supporting Hamas Directly, and Hizbullah is supporting Hamas, So there is no need of Hamas to interfere in Syrian situation, they have to look after their problems with Israel regime.

Nice analysis.
One stake holder's role is missing i.e Hamas. What are they doing?

Thanks @WisdomGateway for uploading. Masha'Allah impressive analysis by Agha Naqi. Good information and even better conclusions.
