From a strategic stand point, this strike did not achieving anything for Israel. The only strategic loss here for the PIJ is the loss of the commander of the north Gaza Quds Brigades. Israel's struggle is with Hamas and the rise of resistance operations in the West Bank, where PIJ has influence in. And Hamas is trying to unite all fronts and activate them from a popular sense.
The response against the death of the Palestinian prisoner was claimed by the JOR. Israel responded with a targeted strike against PIJ commanders. This puts Hamas in a awkward position, and Israel is trying to scare Hamas from taking a more active role in the West Bank.
PIJ will sometimes play the role of absorbing the Israeli response to avert a wider war against Gaza, and will continue to face this predicament if it doesn't evolve politically. On paper it looks like it can be relatively formidable, but it's issue is lack of military and political maturation. Which results in PIJ not being effective at exploiting opportunities despite having better resources at its disposable compared to smaller factions in Gaza.
Now to the response:
The decision to not respond immediately is the right decision here. As Israel was prepared to minimize its losses. It's better to keep Israel on edge until a opportunity presents itself to avenge the killings. I'm not entirely convinced Hamas will join with its full force, could be wrong, but it makes no sense for them from a strategic perspective. Instead, I see them playing an advisory role for the PIJ and providing them intelligence, political backing, and potentially carrying out border strike reprisal on behalf of PIJ while attributing it to the PIJ. And taking part in the initial rocket barrage that will follow, then placing the ball in Israel's court.
Hamas's much more mature as a political and military organization, and organized. And chooses the right time to respond to Israel's ongoing war on Palestinians and chooses best on how to respond as well. I don't see Hamas leadership in Gaza seeing this as a good time for many reasons that I won't get into to. With that all said, I expect something to happen next week in relation to events in Jerusalem. And PIJ will need to exercise some strategic patience and follow Hamas's lead if it wants to exercise the most effective option.
