Hamas always wanted a slow deal, with hostages released in small numbers over months, followed by an end to the war.
It assumed that once Israel stopped fighting, inertia would keep the war from restarting.

Today, with Trump and Witkoff no longer laser-focused on the deal and instead dealing with other issues such as Russia and Ukraine, Hamas assumes that it can go back to the way things were in the summer and fall of 2024

However, Hamas has a trick up its sleeve.
It remembers March 2024 when it got Israel to basically do a de facto ceasefire during Ramadan.

At the time, the Biden administration pressured Israel to reduce the intensity of fighting in Gaza.
Israel did so, and Hamas got a reprieve. Now it wants even more.
