I would expect the Israelis to hunt down and kill every Hamas leader that they don't find in Gaza.
Operation Wrath of God which followed the 1972 Munich massacre of 11 Israeli Olympic team members would be the template. And this time, since we are talking the slaughter of 1300 people, including dual-nationals and foreign citizens, the Western governments might be more inclined to turn a blind eye to any mysterious deaths on their territory.
