Strategically, this does drive a wedge between Hamas and Iran. Of the likely successors, Mashaal has had multiple conflicts with Iran, Abu Marzouk is a pragmatist who would probably start de-escalating, and al Hayya who is a hardliner. For two of those three, Hamas moves away from Iran which is probably a good thing for Israel.

Only time will tell though
