Yahya Sinwar, the architect of the October 7 attacks on Israel, has been named the new political leader of Hamas following the assassination of Ismail Haniyeh. Israeli officials, including Foreign Minister Yisrael Katz and IDF Spokesman Daniel Hagari, have vowed to eliminate Sinwar, whom they consider a top terrorist. Sinwar, known for his ruthlessness and connections to Iran, has been in hiding in Gaza. His appointment comes amid escalating tensions and a severe humanitarian crisis in Gaza, where nearly 40,000 Palestinians have died. The U.S. has expressed hope that Sinwar will negotiate a ceasefire, although experts believe his extreme stance and coordination with Iran make this unlikely. Sinwar's leadership marks a consolidation of Hamas's Gaza-based faction and a shift towards more hardline policies.
