What response did Hamas anticipate from Israel?

 Here’s a revised version with more complex phrasing and extended wording:

Hamas and Iran anticipated Israel's response to unfold precisely as it did. However, Hamas also calculated that Iran and Hezbollah would intervene on their behalf by launching coordinated offensives from the northern front. They did not expect to be abandoned, left to shoulder the full brunt of Israel's retaliatory measures independently.

Hamas did not foresee Israel's capability to rapidly mobilize a staggering 320,000 reservists within just a matter of days, nor did they anticipate Israel’s capacity to strategically cycle these reservists in a manner that would prevent the economy from grinding to a halt, all while sustaining a proactive military initiative in Gaza. Additionally, Israel’s formidable show of force in the north was designed to exert overwhelming pressure on Hezbollah and Iran, effectively dissuading them from intervening.

Iran, for its part, failed to predict the forceful "Don’t" speech delivered by President Biden, followed almost immediately by the deployment of two U.S. aircraft carriers—a move aimed squarely at the potential eradication of the Iranian garrison stationed in Syria.

Have I overlooked any critical details?
