As long as the US remians in Syria, none can touch Israel and this is the crux of Israel's strength.
This is just my opinion but one of the ways Israel controls Syria is through US presence and since the US has started getting out in a gradual manner, Israel has been in a state of paranoia with every passing day Israel trying even more radical shit to rile the people up, cause havoc, and (if possible) come up with an excuse as to why the US needs to stay in Syria.
That is why I believe the reason Turkey is keeping quiet is to prevent Israel from coming up with any sort of excuse to try and prevent US forces from leaving. Turkey is now keeping quiet until the US leaves but when it leaves, I think Turkey is gonna go all in within Syria. Erdogan's words yesterday clearly stated that he wont accept anything other than unified Syria and that SDF should follow the signed deal either peacefully or not
