Two sworn enemies hold the key to ending the war in Gaza. Does either man want a deal?

The latest flurry of Gaza cease-fire talks — the back-and-forth over now-familiar sticking points and appeals from around the world — obscures a grim truth about the monthslong efforts to end the Israel-Hamas war and free scores of hostages.

Any deal requires the signatures of two men: Israeli Prime Minister Benjamin Netanyahu and Hamas leader Yahya Sinwar.

They are sworn enemies, notoriously tough negotiators and know that the outcome of the talks will profoundly shape their legacies. In Sinwar's case, it could mean life or death.

Both have strong incentives to end the war. But they may also think they stand to gain by holding out a bit longer, and that war is preferable to a deal that falls short of their demands.
