So why did Hamas agree to return all the hostages?

What does Hamas gain from Trump's ceasefire? Why did they agree to it?

Seriously, I don't understand. From their point of view, what do they gain?

There are a few reasons that I can think of:

1. With this ceasefire, their remaining soldiers and political leaders will remain alive.

2. The ceasefire allows Hamas as an organization to survive, although it may have to change its name, and allow some new puppet figure to be their symbolic president.

But that puppet will only be a joke..he will appear on English-language TV shows to lie about how Gaza is a free democracy, being oppressed by the genocidal Jews . The progressives and liberal parties around the world will believe it, but the real power will stay with Hamas, who will control Gaza just like before. But now they will have to take responsibility for re-building and feeding their people. .

3. They regain all the land of the Gaza strip (it will take a year or two, but once Israel starts withdrawing, the world will force the IDF to complete it.)

I think these 3 reasons have a certain logic...but they don't help Hamas reach its main goal : to destroy Israel.

Without this ceasefire--Hamas was already winning the war. (Not the ground war--I mean the REAL war--the war of public opinion..)

From their point of view, keeping the war going was the best way to destroy Israel. The world is already planning boycotts of Israel, (So far, mostly in sports, cultural events, and Eurovision--but real, and seriously damaging boycotts are being planned in many industries.) So if Hamas had kept the war going for another year or two, with more and more fake claims of starvation, etc.. they would do very,very serious damage to the Israeli economy, and maybe to the IDF (England and other countries are already refusing to sell weapons, the Caterpillar bulldozer company may soon stop selling to Israel, etc).

So-why did Hamas agree to Trump's deal?

Is there any real, hard evidence that all the destruction is actually affecting Hamas? Are they afraid of losing support from their people?
