I think it'll go better considering both US and Israel both have successfully weaken Iranian regime considerably. And don't be surprised if we get to see a new political setup in Iran very soon. I don't believe that this ceasefire has got approval from Khammeini.

TBH Israel has abided by them. Look at 2008 brokered by Egypt.... Hamas and Islamic Jihad would stop but then as soon as Israel troops left they violated it.

Gaza is something that Israel has tried to give back to Egypt that they do not want. It is clear to everyone that Hamas cannot be in control or armed within the Strip. They have been at the forefront of launching attacks against Israel and to really hammer it home look at what Egypt has done. They build a huge ass wall and help Israel with the sea blockade. They know Gaza is an issue with Hamas and no one wants to deal with it.
