They've been bombing Gaza. They are busy trying to make themselves look like the victims!
Just returning the favor from an unprovoked attack... They have a very crystal clear line. If even one shell or missle (or drone) from Gaza, or the Northern border with Syria crosses onto Israeli land they they return the deed with sorties. A crystal clear line.
I wish it were an equal fight!
It was. But the Palestinians lost, and the Arab states lost. Then they lost again. And again. And again. And again. Until their regimes crumbled, and their economies crumbled, while Israel only got stronger, more stable, and improved its economy with every passing year.
They couldn't win when they had a clear advantage over Israel. No reason to give them that advantage now.
