My view is that the Israelis should not invade Gaza. Hamas was aware that this would be the result, since this is always the result, and they carried out their attack anyway. Why? Maybe they wanted Israel to attack. My view is that when the Israelis attack, they cannot avoid killing women and children. Pictures will show their troops inside a decimated area, dead Palestinians from the cleaning out process all over the place. Once again, Israel will be considered the aggressor and the antisemites here and in the world will have a field day demonizing all Jewish people simply because they are Jewish people. Other anti-Israeli countries may join the Frey, and all-out war will engulf the Middle East.
On the other hand, Netanyahu will use this attack as a way for him to stay out of prison (where he belongs) as he is most certain to be convicted for corruption if not for his incursion. Their legal system is now focused on Hamas and not on him. Wannabe dictators love this ploy.
My thought is that when in Rome, do as the Romans do. Send agents into Hamas territory and keep them on the defensive with sniper fire, bombs placed in strategic locations, small incursions,
some missiles here and there. Of course, the tunnels (paid for with financial aid from other countries) where Hamas is hiding need to first be demolished, and that comes first.
