As Zionists see Palestinians as "human animals", it is not likely that they will be able or willing to keep any agreements with Palestinian people who are not seen as human, therefore Israelis only laugh and keep going, knowing that if they get caught doing evil, they will simply say "Arabs are terrorists".
Overwhelming racism against Palestine in the West will only support Zionists.
Until Palestinian resistance is recognized as lawful and legitimate, especially in the West, there will be no real agreements and no ceasefire either.
