Hamas
Palestinian Hamas militants are seen during a military show in the Bani Suheila district on July 20, 2017 in Gaza City, Gaza.
  • Israel appears to be preparing for a ground invasion of Gaza where it hopes to wipe out Hamas.
  • But experts on peace and terrorism said a strictly militaristic approach is unlikely to create change.
  • "It is extremely rare for a terror group to be wiped out with violence," one expert said.

Israel has declared a state of war and vowed to destroy Hamas after the Palestinian militant group executed a wave of unprecedented terror attacks throughout the country that killed more than 1,000.
