assad was just another useful idiot for isreal. No different then how the houthis are presenting themselves these days.
He was enemy to isreal, but he was also extremely useful. You see from the isreali perspective all these muslims or rather "goyim" are enemies, the question is which ones can also be used to further isreali agenda, assad was that guy. He kept syria weak and when the civil war started he contributed to the nation ruining itself and on the verge of balkanisation. This desperate situation allowed the isrealis to cut deals with assad that would favour isreal too.
Now remember the reason all these zionists are panicking, is because Turkiye can contribute to building a strong syrian state backed by a strong Turkish military with strong rapidly advancing military technology.
What Syria can become with Turkish backing, is not something that assad ran syria could ever wish to have become with iranian backing.
Infact the iranian model forces you into a corner and internationally isolates you. These destroys your economy and your ability to develop a strong military. Compare the syria today led by Turkiye, removing sanctions and embargoes, opening the nation to the world.
Isreal likes her enemies isolated, embargoed, devoid of allies and boxed in from all sides. Turkiye will not create that syria for isreal.
