Gaza rejecting the ceasefire does not simply mean they want war. The people of Gaza are getting sick and tired of living in a place were you feel like your in a prison. So when Israel offers a ceasefire, it can only mean, We shall attack you more and kill more of your people.
This kind of situation is quite disturbing.
How would they feel if this happens to them? The people of Gaza wasn't prepared. They didn't know that this will happen. Now all they can do is pray and hope everything will be okay.
