I've outlined how it would have been different under Trump.

You've outlined how events under Trump might have been different after the attack. But not how Hamas' pre-attack choices would have been different.

Hamas planned and launched this attack entirely based on local and regional considerations. They were dismayed at the growing rapproachement between Israel and Saudi Arabia, which itself was driven by those countries' inherent economic and security interests. They felt domestic political pressures (ie. internal to Gaza) to provide some sort of military action against Israel more effective than just launching a few scattered rocket strikes. They began to recognize that Netanyahu's plan to marginalize them by handing them Gaza in a de facto normalization of the status quo was not working for them. And they believed that they had identified security failures that would be sufficient for them to grab a few Israeli hostages, preferably a member of the military or two, which is currency in their dealings with Israel.

None of those factors involve the U.S., or is in the slightest bit affected by the U.S. There's no reason to assume that the U.S. would be relevant to Israel's response to the attack, since it was expected to respond in some minor border skirmishes and an exchange of hostages - not the full-scale invasion of Gaza.

Again, not everything is about us. Sometimes events happen in the world because of things that don't involve the U.S.
