Size, Scale, Intensity, and Intent.
All are different here.
Yes, Hamas and Hezbollah are the IRGC's remote occupying armies in the adjacent territories of Gaza and Lebanon, and they have launched rockets into Israel on a near-daily basis for years.
The difference is Ham/Hez rockets are small, unguided, generally aimed at residential or commercial areas to cause disruption, and are generally low-intensity and are routinely intercepted.
The differences are:
1) The attacks from Iran are large warheads on intermediate range ballistic missiles, with precision targeting.
2) They are fired in coordinated barrages along with drones and other rockets specifically intended to over-saturate the Israeli missile defenses.
3) The attacks are also targeted specifically at industrial infrastructure with the intent of causing maximal damage to the world economy.
4) The targeting uses high-precision satellite data and intelligence from Russia and China to cause maximum global damage.
Those are major differences in both quality and quantity of the attacks.
Before, the risk was relatively low: not targeting this type of industrial site, not using high-intelligence and high-precision targeting, not saturating, and using small warheads unlikely to cause major damage.
The situation since 28-Feb-2026 is entirely different.
