That sounds about right. Iran's Islamic dictatorship is full of rats like Khaddam.
This Khaddam has a very long well known history of being one of Syria's top Baathist enforcers, a real thug. Harari's assassination was most likely fined tuned by Syria's top man in Lebanon, plus other hits of prominent Lebanese ordered by Damascus.
"Lebanon will either be united or will be returned to Syria," All of a sudden he is quiting the Syrian régime? Something stinks here.
A brief look back at Khaddam:
Abdul Halim Khaddam, Vice-President
Born in 1932, Mr Khaddam has exercised considerable influence for three decades and is regarded as a leading hardliner.
A Baath Party official in the 1960s, he became foreign minister and deputy prime minister in the 1970s.
In 1984 Mr Khaddam was promoted to the vice-presidency, and has worked to assert Syria's dominance over Lebanon. "Lebanon will either be united or will be returned to Syria," he said in 1976.
He remains fiercely opposed to any loosening of the Baath party's grip on power.
In a newspaper interview last year, he said that those who suggested changing the regime either did not understand that this would jeopardise the "stability of the state" or "serve the plans of foreign elements and of Israel".
"In exchange Syria offered to house Iran's nuclear and biological weapons if they are attacked. Evidently they are attempting to capitalize on their experience hiding Saddam's arsenal."
I believe your overview is right on target.
