I think there is a small but non-zero chance that the killing of Yahya Sinwar might open a window for a ceasefire before election day.
I don't think it's wise for the Harris campaign to count on that.
The Netanyahu government has been back channelling with the Trump campaign for months, and right wing Israeli politicians have been saying publicly that a Democratic victory is bad for Israel.
I doubt that Netanyahu will bend over backwards to save her campaign.
