Yahya Sinwar's Killing Has Left Hamas in Disarray

Almost exactly a year after Hamas's horrific attack on Israel, its leader Yahya Sinwar has been killed. This is not the end of Hamas, but it does offer Israel an opportunity to destabilise and fragment the group, similar to what Israel has done to Hezbollah - to cut the Islamists down to a more manageable size and bring the war to a conclusion on terms reasonably close to victory.
