According to Daniel Byman, a professor at Georgetown University’s School of Foreign Service, the killing of Yahya Sinwar, the recently elected head of Hamas' political bureau, may turn out to be less impactful than anticipated in the current war on Gaza.
While Sinwar's death only means one less leader in the Palestinian Resistance, Hamas is far from rescinded as "Israel" faces the more complex challenge of the day after in Gaza.
Byman writes in Foreign Policy that despite Hamas suffering the loss of many of its leaders like Ismail Haniyeh and [allegedly] Mohammed Deif, the Resistance will still have new less-experienced members ready to take over.
