While I agree with you that anyone who messes with our holy sites should be exterminated from the world, what are we gonna do? The whole Muslim world against Israel will lose. Why? Because, supposing no nukes are ever used, the US and European countries, mainly France and Britain will come fast for Israel's rescue.
Even if that doesn't happen, there's Israel's "Samson Option". It means that Israel will use nuclear weapons as a last resort if their existence is ever threatened. We can use Pakistan's nukes in response, but then what? More Israeli nukes, more destruction than ever expected.
The scenario which I said couldn't ever happen was talking about Syria's invasion of Lebanon and taking out Hezbollah.
With all due respect, you're terribly mistaken. You want to tell me that Egypt and Jordan are currently free countries? My friend, all Arab countries are sadly puppets of the USA and the west. This cancelled gas deal is most probably nothing more than a joke and a good trick played by Egypt's SCAF to stay in power.
As for Al Assad, of course not. I wouldn't support a murderer. He forced people by torture to say " لا اله الا بشار ".
