Netanyahu wont sign a ceasefire, the stated policy is to remove Palestinians from Gaza and that wont change, the only pressure he would respond too is from Trump plus when the war ends, so does his government and him... he has no interest in seeing it end at all.
As to Hamas being destroyed, no they are not, they may well be weakened immensely but as an idea/ideology, they are alive and kicking...perhaps stronger than ever, in terms of recruits, they are fluid, its like a Hydra... kill one Hamas terrorist and 2 replace him/her, they may not have missiles and weapons - yet! - but it is their hearts.
Some Palestinians will seek revenge on Israel for evermore and throughout the world too.
