The Israeli government is internationally pressed from all sides, diplomatic, military, social, etc. It should be made clear that there will be physical hurdles as well if it decides to go on with the attack.
Israel closes down the Aljazeera news channel in Israel because free information from all sides is a threat in this situation. Internationally, however, it is not sufficient that people are merely informed. The knowledge should push people toward constructive activism. That is possible if the public is presented by alternative solutions. So news and information about what is going on and the historical background of the conflict alone will not push people toward constructive activism.
If the Israeli government doesn’t accept the ceasefire, that will be the opportunity to kick start that constructive activism because all elements are there.
UPDATE 1:
There are various ways to send humanitarian aid to Gaza. The port the US has built or even sending aids from the air.
