Since the issue of the corridor was raised last month, Hamas has said it will not agree to Netanyahu’s red line.

“At this point, they cannot accept anything short of the demands they are now calling for: A complete cessation of hostilities and the full withdrawal of Israeli troops,” Mustafa said. “If they were to accept anything short of what they’re demanding, that would be political suicide for the movement.”

Netanyahu’s defiant speech on Monday may have extinguished hopes that the killing of the six hostages could lead to a change in course. Former IDF spokesperson Lt. Col. Peter Lerner, who has become more critical of the government since leaving his post earlier this year, said about the remaining hostages after Netanyahu’s speech: “He sealed their fate.”

The insistence on maintaining troops along the corridor may also spell further tension between Israel and the United States, which has throughout the months-long negotiations insisted that Israel must fully withdraw from Gaza after the war.

When asked Monday whether Netanyahu was doing enough to reach an agreement, President Joe Biden said simply: “No.”
