Biden administration officials are celebrating the death of Hamas leader Yahya Sinwar at the hands of Israel Defense Forces as a triumph of justice over evil, but also as a key opportunity to settle the war in Gaza by relaunching negotiations aimed at securing a cease-fire and the release of the remaining hostages in the enclave.

Amongst a long list of questions and speculations following Yahya Sinwar's death, what stands out as the most crucial one is who will be appointed as the next Hamas chief. The decision is pivotal as the leadership in several ways is expected to set the tone for future moves.

Yahya Sinwar, widely regarded as mastermind behind Hamas' brutal attack on Israel last year, was killed in Israeli military operation in Gaza.
