With dawn fast approaching in Palestine I think we can potentially draw 4 conclusions:
1. The Israelis have greatly degraded Iran's launchers that they can only send a handful of ballistic missiles per salvo, essentially destroying any kind of way Iran can hit back since in order to make significant damages to overcome the Iron dome you need to be shooting at least 50 missiles at a time (at a bare minimum).
or
2. The widely held intelligence reports that Iran only had 2,000 ballistic missiles before the war were true and we simply can't sustain barrages of 100+ missiles per day for longer than a few weeks and the IR is trying to conserve its weapons
or
3. Iran has lost both its launchers and its missiles and has lost all forms of deterrence against Israel thus are total sitting ducks.
or
4. The government is in the planning phase of something big within the next 24 hours and was using today to regroup (I find this unlikely)
