I asked myself why Hamas attacked the music festival in such salvage manner to anger the world? Why did Hamas do something so stupid and caused the loss of Gaza strip and suffering of civilians. Then Hezbollah was forced to response to show support for Hamas.
It appears to me that their sugar daddy IRAN is using them as a proxy to fight Israel so that Muslim world (especially Saudi) dare not make peace with Israel.
One step deeper, when things happened, we asked ourselves who is the benefiticary eventually?
In recent years, Hezbollah is less obedient to Iran than Hamas or Houthi. Hezbollah's leader Nasrallah is also more charming than IRAN's supreme leader and many deemed him to be a direct descent of Prophet Muhammad. The removal (killing) of the whole Hezbollah leadership works in IRAN's favour and they can introduce new puppets.
Lastly, look at this week and the previous missile attack by Iran on Israel. Like putting up to show for their supporters but afraid of severe Israeli reactions, IRAN's attacks were polite and limited, with ample warnings and infrastructures/civilian centres were mostly avoided. After which, IRAN will always proclaim that they have "concluded their revenge" and will retailate only further if Israel retailates.
Conclusion: IRAN's supreme leader is a jealous and ball-less man.
