“In war, setbacks often divide; successes usually unite. Guardian of the Walls—thwarting the terror tunnel network and the naval and aerial capabilities that Hamas built over many years—was our most successful operation against Hamas to date. Cumulatively, the best indicator of the success of our operations was that in the five years after Protective Edge in 2014 up to the end of 2019, the population in the Israeli communities adjacent to Gaza grew by 15 percent, compared to 9 percent in the rest of the country.3 That robust growth continued after Guardian of the Walls. Yet during that operation, in addition to Hamas and Islamic Jihad rockets on our cities, we faced another ominous threat. Israel has several cities with mixed Jewish and Arab populations. Normally they coexist peacefully and harmoniously. Now, in the midst of the fighting, groups of radicalized Israeli Arabs attacked their Jewish neighbors with automatic weapons, murdering them in apartment buildings and in the streets. The shooters, often an amalgam of Islamic radicals and criminal elements, were using illegal weapons rampant in Arab communities. This lawlessness was a festering sore for decades.”
