I'd been waiting to see how things were turning out before posting, but we have today -IMO at least - a first indication that
There is an interesting piece on Southfront (and yes, I know it's a pro-Russian site, but please bear with me for a moment). They're acknowledged that 33% of all Surface to Ground missile launchers of Iran have already been destroyed. This, combined with the disruption of Iran's air defenses means, IMO, that The Israeli air campaign is working better than expected. Iran has failed to hit Israel's air force structure (at least for the moment) and is suffering the consequences of allowing the IA F to roam freely in their airspace.
Not posting the link, IIRC it's forbidden to link to SF here, but the title of the piece
Israel Maintains ‘Aerial Superiority’ Over Tehran, Hits Dozens Of Missile Launchers (Videos)
Iran is now compelled to move closer to its red lines : launching a ground war (an invasion of Iraq) which will, IMO, unite the Arab world against them (like in the Iran-Iraq war of the 80s), or shutting the Strait of Ormuz, which would have about the same effect with the added bonus of creating tensions between Russia (benefiting from the high oil prices) and China suffering from the same.
Lastly, India throwing their support behind Israel is a huge setback for the Mullahs, and a clear indication that the BRICS are splitting, as could be expected. This is now a war of attrition, since Israel didn't manage a decapitation strike at the outbreak of hostilities, but one Iran seems to be losing which could hopefully lead to the regime's demise.
