It's been a difficult almost 2 years for Israel.
Israel was invaded, with hundreds murdered and scores abducted in October 2023. Within in hours, if not minutes, LIEden & his minions were exerting extreme pressure on Israel not to deal with Hamas the way Hamas had earned.
Despite the difficulty of attacking Hamas, which was dug in deep within and under civilians and "schools" and "hospitals", Israel defied LIEden's pressure, and Hamas is now largely dismantled, flayed, and eviscerated. When LIEden left the WH, Trump told Israel to go at Hamas full force.
In the same time frame, Hezbollah reared their ugly semi-coordinated (with Hamas) heads, and after Israel destroyed many of their weapons and decapitated Hezbollah's leadership at the midriff, they are reeling and the government of Lebanon is, for now, telling Hezbollah what to and not do.
After their proxies got hit, Iran thought it wise to let fly at Israel with missiles that accomplished little. Israel responded by taking out part of Iran's SAM and AA capability along with part of Iran's missile stocks and production capacity. It was a forceful FAFO warning.
Iran had been freely supplying weapons, materiel, and leaders/advisors through Syria, with the cooperation of Assad's government. Israel's Operations Grim Beeper and Stalky-Talky cramped Iran's style, and the fall of Assad to rebel groups now too busy consolidating their power to get into conflict (for now) with Israel severed Iran's ties to their proxy in Lebanon.
How badly remains to be seen, but Iran's Houthi proxies got a fair amount of pounding from the US and from Israel, so they may be laying low for a while, and Iran's ability to sneak weapons in to Hamas has been reduced significantly, if not cut off.
All of the above is context for where we are. Iran's proxies have been defeated or suppressed in detail. Hamas, Hezbollah, and the Houthis can't force Israel to divide its efforts. Syria isn't in a position to interfere with Israeli overflights, and after Iran having been semi-allied with Assad, probably is not inclined to help Iran. Iran's antiaircraft capabilities were diminished months ago, with its supplier, Russia, being unable to replenish (courtesy of Ukraine).
Then Israel taught Iran to hate Friday the 13th, some of the earliest lessons being the destruction of even more Iranian radars and SAMs. Between successful SEAD and the Iranian air force's collection of aging F-14s and F-4s being less than well maintained and being significantly less capable that what the Israelis are flying, Israel pretty much has total air supremacy. Israel can choose and attack at will whatever they consider important - nuclear facilities, military bases, military command & control, civilian leadership, naval and port facilities, oil refineries and production. If Israel chooses to hit the water and/or electricity supplies to Tehran, millions of people will suffer, very quickly.
