I agree it's more complicated, but it doesn't change what I wrote.A weaker Iran means a weaker Russia and vice versa.If both are weakened, Assad is weakened.But I guess it's not as clear cut with Turkey. Although the Kurds will have an easier time when they won't have to fight Iranian, Syrian and Russian forces along with Turkish ones. And a weakening of Iran will also weaken Iranian-affiliated Iraqi militias that are also attacking Kurds.

Russia didn't let Israel, one of their bases were shot at for 40 minutes straight as a warning.They also got a bunch of other warnings before and after. Russia won't waste their time on this when they're already losing so much in the war with Ukraine.

Both Russia and Iran helped Assad in the civil war.

Israel is allied with Azerbaijan because of their border with Iran.

Turkey was already assisting Hamas even before. They'll keep trade with Israel behind the scenes for economic reasons like they've always done.And at the moment Russia is assisting Turkey in bombing the Kurds.
