So the Iranians can smuggle in a giant missile that can travel 99 miles (washington dc to richmond va), but they can't smuggle in drones, atgms, landmines, and other assorted goodies that would turn Gaza city into a death trap? Or send advisors to train Hamas fighters in urban warfare or warfare in general?
According to
Wikipedia the IDF has lost 52 soldiers in three weeks of ground operations in Gaza. About 2.4 soldiers a day. For comparison, the US lost 54 soldiers in 9 days during the
second battle of Fallujah. About 6 soldiers a day. And what makes these numbers worse is that Hamas has had since 2014 to prepare for this. The jihadists in Fallujah had six months and 11 days.
