I am going to crosspost something I saw an Israeli post elsewhere. Take it with grain of salt. I don't agree with all of this analysis but some points they made are interesting:
Why would Hamas waste 3,500 rockets and missiles on Iron Dome, in 6 days? Isn't it really stupid, after seeing on Day 1, that Iron Dome intercepts virtually ALL missiles, to keep launching? Same story for day 2. And day 3. And day 4. Iron Dome intercepting over 99% of your rockets. But they KEEP LAUNCHING them. How many rockets can Hamas have? 10-12,000 or so? At this pace, in 2 weeks, they go back to throwing stones at Israel, or, at best, mortars and bottle rockets. Nah, something else is afoot, and Israel is most likely going to be attacked by Hezbollah in the coming days.
HISTORICAL REFERENCE
During the 2006 Lebanon war, Hezbollah launched 4,000 rockets/missiles toward Israel, in 33 days, or roughly 121 / day. Hamas launched 3,500 in the last 6 days, or roughly 583 / day. In other words, Hamas today is 5 TIMES more powerful then Hezbollah was 15 years ago. How much more powerful is Hezbollah then Hamas? Probably 10 times more powerful. Hezbollah is believed to have up to 100,000 rockets and missiles, most of them far better then Hamas. If Hezbollah and Israel would clash again today, like back in 2006, Hezbollah can easily launch thousands of missiles and rockets, on a daily basis, for weeks in a row. Can Israeli Iron Dome match 500-1,000 rockets barrage? Well, we don't know, since there was no such barrage against Israel. But Hamas, who, as Hezbollah, is under Iranian patronage, launched several barrages between 120 to 250 missiles/rockets against Israel, during this current conflict. How better can Iran test Iron Dome capacity and capability, then by using the little child (Hamas) and their rockets, and not waste their big child (Hezbollah) missiles? If my assumption is correct, there won't be a ceasefire, we will see a barrage of up to 500 missiles launched by Hamas in the coming days, which will test Iron Dome breaking point. So Hezbollah, which is primed to attack Israel, will likely do so, with far larger barrages, of much better missiles, with better accuracy and power. It seems totally counter-intuitive for Hamas to just throw missiles into Iron Dome's grinder...unless they are testing it for someone able to launch more and better rockets/missiles, for longer periods of time.
