Global observers are divided on the significance of Benjamin Netanyahu's war Cabinet's killing of Yahya Sinwar, but there is consensus that it opens new possibilities for a ceasefire deal. Netanyahu's government has not shown a positive response to calls for an immediate cessation of hostilities. The elimination of Hamas leaders and claims of breaching the 'Gaza support front' have emboldened Netanyahu's war Cabinet. World leaders must now use their diplomatic influence to impose their will and halt the destruction in Gaza.
