The exchange was an illustration of months of tensions between Netanyahu and the country’s military leadership, who argue that Hamas could only be defeated if Israel replaces it with another governing authority in Gaza. During more than eight months of war, the Israeli military has invaded swaths of the Gaza Strip, only to see Hamas reconstitute itself in areas when Israeli forces withdraw.“What we can do is grow something different, something to replace it,” Hagari said Wednesday. “The politicians will decide” who should replace Hamas, he said.
