#2 is the big deal. Hamas (quite reasonably) thought they'd get more support. Other than thr Jew-hating Western left, they really haven't so far.

It was rational for Hamas to launch this war, as Israel was getting close to normalizing relations with many Arab states. Hamas will succeed in stopping that temporarily. But if Israel continues to  use violence against them the cost will likely be the destruction of Hamas.

The most important thing for Israel to do is to not succumb to ceasefire pressure and actually finish the job. Tens of thousands of Hamas and Hamas supporters need to be killed, and the infrastructure of Gaza needs to be destroyed. And all this needs to happen with minimal IDF casualties, which means they should not risk IDF lives for Gazan lives. 

 Yep, and it looks like they are definitely not going to succumb to ceasefire pressure. This time it’s different. 

 It was probably the worst massacre of Jews since Hitler. Unlike the Holocaust, it was documented extremely well while it was happening. And on top of all that, lots of the left wing west is straight up celebrating it, even though they most likely know what actually happened.

Under those conditions, it's reasonable to believe that most of the people pushing for a ceasefire would murder you if they had the chance.
