Hamas Has Deadlier Weapons Than the Last Time Israel Invaded Gaza

The last time Israel invaded the Gaza Strip nearly a decade ago, its troops pummeled an overmatched Hamas fighting force. They destroyed tunnel systems and sealed off smuggling routes, costing the Islamist group two-thirds of its missiles by the time they withdrew. 

Now, as Israel steps up a new invasion, it faces a more-potent enemy that has rebuilt its arsenal with help from Iran. Since the operation started on Oct. 27, Hamas has attacked the Israeli army with explosive-laden drones, anti-tank missiles and high-impact rockets—the sorts of weapons that have transformed the battlefield in Ukraine.
