The UN peacekeeping force in Lebanon has failed to prevent Hazbollah from operating in and militarizing the border with Israel, and the UN peacekeeping force on the israeli-egyptian border in 1967 dispersed when the egyptian army mobilized, marched on Israel, and ordered the peacekeepers to vacate. Israel has 0 experiences where UN peacekeepers uphold their mandates and actually keep the peace. Israel has no reason to agree to a failed formula.
